Moonlighter 2: The Endless Vault Update Bugs & Crash Fixes

Moonlighter 2: The Endless Vault shipped its 1.0 build on September 2, 2026, and players immediately began documenting the latest Moonlighter 2 update bugs across Steam, Reddit, and the official Discord. This guide consolidates the Moonlighter 2 known issues list, every Moonlighter 2 crash fix shipped so far, the broader Moonlighter 2 optimization update cadence, the still-pending Moonlighter 2 Game Pass sync question, and the surprise Moonlighter 2 price increase that landed right before launch. If a soft lock, a corrupted relic save, or a Cloud desync has eaten your afternoon, the workarounds below reflect the latest community-confirmed status.

Moonlighter 2 Known Issues at 1.0 Launch

The 1.0 patch delivered Boss Rush, the Moloch finale, and the shopkeeping contest, but it also introduced a wave of Moonlighter 2 known issues that Digital Sun has been triaging since launch day. According to the Steam News hub for Moonlighter 2: The Endless Vault, the team has already acknowledged the bulk of these reports and pushed several hotfixes to address them.

Crash and Soft-Lock Reports

Hard crashes top the Moonlighter 2 update bugs leaderboard, with three recurring scenarios. First, players who alt-tab during the Moloch phase transition occasionally hit a black-screen crash that requires a full restart. Second, save files corrupted by a mid-run force-quit prevent the next session from loading past the Tresna title card, and the only confirmed Moonlighter 2 crash fix is reverting to a manual Steam Cloud snapshot. Third, the Boss Rush end-of-run screen has a 2-3% crash rate on Steam Deck when the player has the shopkeeping contest perk bar at maximum stacks.

Visual, Audio, and UI Bugs

Beyond the headline crashes, community reports of Moonlighter 2 update bugs include a handful of cosmetic and UI defects. The relic tooltip sometimes displays the wrong Perfect Price tier on the first hover, and the Tresna shopkeeper NPC dialogue can desync from the audio VO after a long rest cycle. The DX11 lighting flicker reported during Early Access was largely resolved by the August performance Moonlighter 2 optimization update, but a small subset of players on older NVIDIA drivers still sees flicker in Aeolia.

The Post-Launch Hotfix Cadence and Moonlighter 2 Optimization Update Work

Digital Sun has committed to a fast hotfix cadence that mirrors what players saw during the Early Access era. The official Moonlighter 2: The Endless Vault Steam News hub shows three hotfix drops in the first two weeks after launch, each one targeting the highest-voted Moonlighter 2 known issues.

What the Latest Hotfix Actually Patched

The most recent Moonlighter 2 optimization update addressed four categories of issues. Memory leaks in the Kalina biome were causing frame-time spikes after 45-minute runs, and the patch moved the asset streaming to a worker thread that holds a much steadier 60 FPS target on mid-range hardware. Cloud sync collisions during the shopkeeping contest were resolved by adding a per-save hash check before the upload commit. The poison path mini-boss soft-lock, which trapped players in a no-clip arena, was fixed by reverting the arena collision mesh to its Early Access version. Finally, the Moloch phase-3 projectile VFX desync was patched by re-linking the hitbox to the visible model.

Moonlighter 2 DX11 Fix and Steam Deck Verification

The Moonlighter 2 DX11 fix that landed during Early Access carried over into 1.0, and the game is now Steam Deck Verified according to the Steam store page. Players on legacy DirectX 11 drivers should still force-update their GPU driver and launch the game via the -force-dx11 Steam launch option as a belt-and-braces Moonlighter 2 crash fix. If you want a deeper look at how that performance Moonlighter 2 optimization update reshaped the mid-game experience, the New Bosses & Performance Update breakdown covers the same patch cycle in more detail.

Moonlighter 2 Game Pass Status and Cross-Platform Sync

One of the most-asked questions on the community FAQ board is whether Moonlighter 2 Game Pass is on the roadmap. The short answer, based on the official Digital Sun Games site, is that PC Game Pass availability is still being negotiated, and console Game Pass is not part of the announced launch window. Players who bought the Steam version are not seeing cross-progression parity with any Microsoft Store listing because no Microsoft Store listing exists yet.

Cloud Save and Cross-Play Behavior

Until the Game Pass question resolves, the only confirmed cross-platform path is Steam Cloud, and that path is itself the source of several Moonlighter 2 known issues. Players who switch between a desktop PC and a Steam Deck occasionally see a "save is older than cloud" warning that requires a manual merge. The most recent hotfix added a hash check, but the manual merge flow is still the safe path when the prompt appears. A second Moonlighter 2 Game Pass-adjacent issue is that PS5 saves are not currently cross-compatible with the Steam version, and the PS5-specific fixes shipped in the latest patch only address platform stability, not save portability.

Moonlighter 2 Price Increase and Storefront Changes

Right before the 1.0 launch, Digital Sun quietly applied a Moonlighter 2 price increase across several regional storefronts, which caught returning Early Access backers off guard. The base game moved from its launch-EA tier to the full retail tier, and regional currency conversions triggered a larger jump in some markets than in others. According to the Steam store page, this Moonlighter 2 price increase is permanent and is not expected to roll back, though regional sales events will continue to discount the title.

What the Price Change Actually Means for Players

The Moonlighter 2 price increase applies only to new purchases, so anyone who bought the game during Early Access retains their original purchase and all EA perks. Players who held off on buying to wait for a launch discount will not see a deeper discount than the standard regional sales rotation, because the new baseline price is the reference point. Community sentiment on the Moonlighter 2 price increase is mixed, with the most common counter-argument being that the 1.0 build ships with Boss Rush, the shopkeeping contest, and the Moloch finale, which were not in the EA roadmap at the original price.

Practical Workarounds and the Best Moonlighter 2 Crash Fix Right Now

If you are still running into Moonlighter 2 update bugs after the latest hotfix, there are a few community-tested workarounds that hold up well until the next patch. The single most reliable Moonlighter 2 crash fix is a manual Steam Cloud snapshot before every Moloch attempt, because the boss arena is the highest-risk area for force-quit corruption. Players who hit the Kalina frame-time spike can cap their FPS to 60 in the launcher and disable background recording software, which resolves the issue on most mid-range GPUs.

A Pre-Run Checklist That Actually Prevents Issues

The following checklist, distilled from community testing reported by players across multiple threads, prevents the majority of Moonlighter 2 known issues from interrupting a run. Run it before each major boss attempt, especially if you have been in the game for over an hour. Many of these steps also reduce the odds of needing a manual Moonlighter 2 crash fix later.

• Verify file integrity through Steam before long sessions

• Manually back up remote and cloud save folders

• Cap FPS at 60 in the launcher if on mid-range hardware

• Disable background recording (OBS, ShadowPlay, Medal)

• Close any overlay that injects into the game process

• Avoid alt-tab during Moloch phase transitions

• Lower the shopkeeping contest perk stack before Boss Rush clears

When to Wait for the Next Patch

Some Moonlighter 2 update bugs are not yet safe to brute-force. The relic tooltip tier mismatch has no working community workaround, and the only fix is the in-development tooltip rebuild. Likewise, the Tresna VO desync after long rest cycles is being patched at the audio engine level, and no current workaround fully resolves it. If your run is hitting one of these two specific Moonlighter 2 known issues, the pragmatic move is to finish your current cycle, avoid force-quits, and wait for the next Moonlighter 2 optimization update drop. For broader context on how the post-launch patches are sequenced, the first-run progression guide explains which systems are most exposed to bugs during a fresh save.

Frequently Asked Questions

What are the most common Moonlighter 2 update bugs right now?

The highest-frequency Moonlighter 2 update bugs at 1.0 are the Moloch phase transition black screen, the corrupted save after a mid-run force-quit, and the Boss Rush end-of-run crash on Steam Deck. The recent Moonlighter 2 optimization update hotfixes have resolved the Kalina memory leak and the poison path collision soft-lock, so those two are no longer on the active Moonlighter 2 known issues list.

Is there a permanent Moonlighter 2 crash fix for the Moloch black screen?

There is no permanent Moonlighter 2 crash fix for the Moloch black screen yet, but the community-confirmed workaround is to disable alt-tab during the phase transition and to never force-quit inside the boss arena. The team has the issue marked as under investigation in the Steam News hub, and a future Moonlighter 2 optimization update is expected to address it.

Will Moonlighter 2 come to Game Pass?

The Moonlighter 2 Game Pass status is still under negotiation according to the official Digital Sun site, and no launch-date confirmation has been published. Console Game Pass availability is not part of the announced launch window, so PC players hoping for a Game Pass addition should monitor the official channels for any updates.

Why did the Moonlighter 2 price increase happen right before launch?

The Moonlighter 2 price increase reflects the 1.0 content scope, which now includes Boss Rush, the shopkeeping contest, the Moloch finale, and all three EA updates. Existing Early Access backers are not affected by the Moonlighter 2 price increase, and the new baseline is the reference for future regional sales events.

Can I get a refund if the Moonlighter 2 update bugs ruin my run?

Refund eligibility follows standard Steam policy, which generally means a request must be filed within 14 days of purchase and with less than two hours of playtime. If the Moonlighter 2 known issues prevented you from playing the game at all, the Steam support team will often side with the player, but a manual Moonlighter 2 crash fix followed by a second attempt is usually faster than waiting on a refund review.
