Moon Sweepers “Could Not Pack a Capsule”: Which Update Fixes It?
Separate the original machine pause bug from the large-base capsule problem fixed in 1.0.5, then check one production route.
Quick answer
Update to 1.0.5 or later. The original machine pause error was fixed in 1.0.4; 1.0.5 fixes packing failures in large bases with many capsules on belts.

Match the symptom to the update
| Symptom | Developer fix |
|---|---|
| Machines pause despite having power and materials | 1.0.4 addresses the original “Could not pack a capsule” error. |
| Packing fails in a large base with many belt capsules | 1.0.5 restores packing with Q, the Auto-Packer and machines. |
Check one affected line
- Close the game and let Steam finish any pending update. Reload the world on the updated build.
- Choose one affected machine. Check its required inputs and available power before changing the route.
- Follow its output. If a capsule is visibly stuck, inspect that connection first. A blocked route is a separate check, not proof of the original bug.
- If packing still fails, record the version, affected machine, solo or co-op state and whether Q also fails. Include those details in a bug report.
Keep the diagnosis small
Do not assume the old message identifies every possible factory failure. Updating addresses the documented bugs; it cannot supply a missing ingredient or repair every layout.
If relocation helps you inspect the route, use the 1.0.5 Move Mode and check one segment at a time.
