Patch Notes & Changelog

The headline change is the J.O.O.N.A.S. cleaning robot rework. Before this patch, many robots stopped working when players walked away, which undercut the whole automation pay-off. DragDrop Games also added new suit gear, rebuilt the Moon map, and cut save times dramatically.

New features

• Night Vision Goggles — a new $350 suit upgrade. Press N to cycle helmet lamp → goggles → off. The developers describe nights as looking "like daytime without shadows," and the goggles are visible on your astronaut.
• Improved Moon Map — right-click to set waypoints, focus the camera or teleport. All robots now appear on the map with their current activity, and each robot type can be toggled on or off.
• Teleport Panel — view and teleport between the stations you have discovered.
• Suit HUD icons — new indicators beside the dust gauge for lamp/goggles, jetpack boosts and gravity boots.
• Helmet lamp upgrades — moved to the supply wall.
• Capsule Catcher — the glass now shows the collected dust, and capacity is increased to 100 kg.

J.O.O.N.A.S. improvements

• No more dock trips — each unit cleans a sector and launches capsules to the nearest catcher from wherever it is, then moves on to the next sector.
• 2x faster cleaning — it cleans one hex at a time from the outside in until that hex is 100% done, cutting circling and idle time.
• Smarter navigation — finds its way around buildings and skips hexes it cannot reach.
• Always working — keeps cleaning even when no players are nearby. This was the single most requested fix.
• Improved bin indicator — the gauge flashes red when full, and looking at J.O.O.N.A.S. opens its information panel.
• Sector tracking — shows which sector J.O.O.N.A.S. is currently cleaning.

Saving & backups

• Much faster saving — saving large, heavily cleaned bases now takes "a fraction of a second instead of up to half a minute."
• Faster quitting — quitting to the desktop or returning to the main menu no longer leaves you waiting on "Saving your progress…".
• Automatic backups — each save slot keeps up to 5 full backups of your world, taken one minute into every session and then every 30 minutes. They are stored outside Steam Cloud at `C:\Users\[user-name]\AppData\LocalLow\DragDropGames\MoonSweepers\Backups`.
• Automatic repair — if a save or part of it is damaged, the game restores it from your backups when the world loads and tells you it happened.
• Crash recovery — after a crash, the game checks your save files on the next start and repairs any that were damaged.

Multiplayer

• Ground synchronization reworked — everyone now sees the same cleaned ground, including robot trails and manual cleaning. No more dust reappearing.
• Shared belt building — any crewmate can place splitters and mergers on belts built by other players.
• Improved mergers — mergers now alternate between their inputs.

Bug fixes & performance

• Fixed all machines pausing with "Could not pack a capsule" even with power and materials available.
• Fixed players falling through the Moon, including after teleporting between stations.
• Fixed foundations not being placeable next to ramps.
• Fixed machines failing to build when snapped side by side.
• Fixed the map not showing full section payments, including the Region Bounty.
• Fixed duplicate chess pieces appearing at stations.
• Fixed overlapping key hints near vehicles.
• Fixed freezing when switching tools while many robots are working.
• Fixed capsules falling beneath foundations after removing belts.
• Fixed a J.O.O.N.A.S. error when re-planning the middle of a hex.
• Steam Deck / Linux — fixed startup issues with older Proton versions.
• Windows / AMD — DirectX 11 is now the default to prevent AMD GPU crashes. To use DirectX 12, add `-force-d3d12` to your Steam launch options.

The first post-launch patch arrived the day after release, alongside a message from the two-person team thanking players and apologising for a rough launch state. It changed how co-op progression works in a way that still confuses returning crews.

• Upgrades now benefit the whole crew — the entire crew uses the host's upgrade matrix. An upgrade bought by any member applies to everyone. Existing saves keep the highest upgrade level any crew member had purchased.
• Host player management — hosts can kick, ban and unban players from ESC → Your Crew. A ban prevents that player rejoining that particular save.
• Garages handle your fleet — each garage can recall, store and upgrade the vehicles you own, and no longer offers an already-acquired vehicle for purchase. Demolishing a garage no longer deletes its vehicles; they move to another garage or wait until the next one is built.
• More flexible placement — splitters and mergers snap directly together port to port, and machines can span multiple foundations, letting pressure chambers, stone presses and garages sit on square foundations.
• Honest payment — payment at the drop-off point now matches the amount on its screen, and dust or stone delivered by conveyor is paid when it arrives.
• World loading — worlds that appeared corrupted even though their saves were intact can load again.
• Save protection — damaged saves are repaired automatically during loading from a backup copy or recent snapshot, with a message when it happens. A check also runs before each save replaces the previous one.
• Performance — the developers report up to around 20% higher frame rates in their own tests, particularly on large bases. Faster teleportation between stations, less stuttering as terrain loads, and terrain beyond the lunar horizon is no longer drawn.
• Version matching — every crew member needs v1.0.3 to play together.

1. Make sure everyone in your crew updates — mismatched versions block you from joining each other's sessions.
2. Know that progression is shared from the host's save; join the right session before expecting your upgrades.
3. Point backups at a safe location — automatic backups live outside Steam Cloud in AppData\LocalLow\DragDropGames\MoonSweepers\Backups, so Steam will not restore them for you on a new machine.
4. If you are on an AMD GPU, the game now defaults to DirectX 11; add `-force-d3d12` to your Steam launch options only if you specifically want DirectX 12.
5. Report bugs in the official Discord — the developers named it as their preferred channel.
