Crashes · Patch 1.0.4
Moon Sweepers crashing
If Moon Sweepers crashes, install patch 1.0.4 before you change drivers or Windows settings. That build repairs a damaged save on the next launch, and it fixes falling through the Moon, capsule-packing stalls, and freezes when you swap tools near a crowd of robots. A launch-week matrix crash is not named in the notes.
Symptom, cause, and what changed
| When it happens | What we can say | What to do | Status |
|---|---|---|---|
| Falling through the Moon, including after a station teleport | Named in the 1.0.4 bug list | Update to 1.0.4 | Fixed in 1.0.4 |
| Every machine pauses with “Could not pack a capsule” | Happened even with power and materials | Update to 1.0.4 | Fixed in 1.0.4 |
| Freeze while switching tools with many robots working | Named in the 1.0.4 bug list | Update to 1.0.4 | Fixed in 1.0.4 |
| AMD GPU crash on Windows | The patch changes the graphics default for this | Stay on the new DirectX 11 default | Official mitigation in 1.0.4 |
| Save looks corrupted or a big base will not load | 1.0.3 and 1.0.4 both repair from a backup | Launch 1.0.4 and read the restore message | Official repair |
| Close while opening the upgrade matrix, or every few idle minutes | Launch-week player reports. Not named in 1.0.3 or 1.0.4 notes | Update, then file-check if it continues | Community report, not confirmed fixed |
Order to try
- 1Install patch 1.0.4 on every machine in the session
Steam should offer it. Saves from 1.0.4 do not open in older builds, so a mixed crew can look like a crash or a failed join.
Official, patch notes - 2Launch once and read any restore message
The game checks saves after a crash and repairs a damaged file from its backups. If it restored something, it says so.
Official, 1.0.4 - 3On AMD, remove a DirectX 12 launch option
Windows now defaults to DirectX 11 to prevent AMD GPU crashes. The flag -force-d3d12 turns that protection off.
Official, 1.0.4 - 4Verify the game files in Steam
Library, Moon Sweepers, Properties, Installed Files, Verify. This is ordinary Steam practice. The patch notes do not mention it.
General practice - 5Update the GPU driver, then try a clean overlay
A current AMD or NVIDIA driver, and turning off the Steam overlay, are common crash steps. They are not listed in the 1.0.4 notes. Try them only after the patch.

Questions
- Does 1.0.4 say the upgrade-matrix crash is fixed?
- No. Launch-week players reported closes while opening the upgrade matrix and while idle. The 1.0.4 notes list other crashes and a save-repair pass. They do not name the matrix. Update anyway, then treat a repeat as unfixed.
- Will a crash eat the world?
- 1.0.4 checks saves on the next start and repairs damaged ones from the automatic backups. It also tells you when a world had to be restored at load.
