Moon Sweepers co-op: version mismatch, shared upgrades and kicking players

Quick answer

Update every crewmate to the same current build (1.0.5 as checked October 28). Older players reported a Steam download-cache workaround for 1.0.3/1.0.4 mismatches; it is not a tested universal fix. Crew upgrades and ESC > Your Crew kick/ban rules remain described below; public games now display a confirmation warning.

1.0.5: update the crew and check the public-game warning

The latest checked patch is 1.0.5, published October 28. Compare the installed version on every PC before joining. The prior 1.0.3/1.0.4 download-cache reports below are dated player workarounds, not a promise that clearing the cache repairs every newer mismatch.

Creating a public game or switching a crew to public now asks for confirmation and explains visitors’ abilities and kick/ban access under ESC > Your Crew. The patch also reports a station-teleport interaction that launched another player off the map fixed. Kingy has not tested co-op or those controls.

Same version for everyone

Moon Sweepers runs online co-op lobbies of up to 16 players. Patch 1.0.3 says all crewmates must be on the same version to play together, and 1.0.4 says its saves can't be opened in older versions, so a crew can't mix 1.0.3 and 1.0.4.

Players on October 26 report being stuck on 1.0.3 while friends were on 1.0.4, even after uninstalling and verifying files. In one thread, clearing the Steam download cache was the only thing that worked, and the update appeared immediately. Don't roll back to 1.0.3 instead: one crew that reverted couldn't join their host's world afterwards.

  1. Check the version shown in the main menu on every crewmate's PC.
  2. If yours is behind and Steam offers no update, clear Steam's download cache, then let Steam update the game.

Shared upgrades and vehicles

Since 1.0.3 the whole crew uses the host's upgrade matrix, and anyone's purchase upgrades everyone; older saves keep the highest level anyone had bought. Your vehicles work at every garage, which can call them back, store and upgrade them, and demolishing a garage moves its vehicles to another one.

Kick or ban a player

Since 1.0.3 the host can open the ESC menu, where Your Crew lists everyone, and kick or ban a player there. Banned players can't rejoin that save until the host unbans them in the same list.

  1. As host, press ESC, open Your Crew and choose kick or ban next to the player.

Splitters and mergers in co-op

At launch, players found splitters and mergers only worked when the host built them. Patch 1.0.3 made crewmates' splitters and mergers work, and 1.0.4 lets any crewmate place them on belts other players built.
