Moon Sweepers: "Could not pack a capsule" and stopped machines

Quick answer

Install the current 1.0.5 update: its October 28 notes report a further capsule-packing fix for large bases, with Q, the Auto-Packer and machines working again. Earlier post-1.0.4 failures are historical; Kingy has not tested recovery on an affected save. Keep backups and report any remaining fault with the installed version.

1.0.5: another named capsule-packing fix

The October 28 patch reports that Q, the Auto-Packer and machines pack again in large bases with many capsules on belts. It removes the old 10,000 loose-capsule limit and allows up to 90,000 capsules in the world. Those are distinct limits; the note does not say every loose capsule can be packed or prove recovery of every affected save.

Earlier player reports after 1.0.4 remain dated below. They do not establish that the same fault persists after 1.0.5, and the new patch note alone is not a Kingy test of a repaired factory.

What happens

Machines that output capsules stop and show "Could not pack a capsule": players name pressure chambers, stone presses and garages. In one report a pressure chamber had power and sand at 10/10 kg but made nothing more. Players first reported it on October 25 before patch 1.0.4, and again within about an hour of 1.0.4 and on October 26.

Earlier 1.0.4 fix and later reports

The October 25 1.0.4 notice reported capsule packing fixed, but players reported failures after that patch. The newer October 28 1.0.5 fix above supersedes advice to wait without a newer notice. Record any remaining fault on the actual current build.

What to do meanwhile

Don't roll back to 1.0.3. The patch notes say saves made in 1.0.4 can't be opened in older versions, and one crew that reverted could no longer join their host's world. 1.0.4 keeps up to five automatic backups per save slot, so your world is safer left on the current version.

One player reports that replacing a stuck machine with a new one gets it working until it sticks again. That's a single report, not a tested fix.

  1. Stay on the current version and let the game keep its automatic backups.
  2. Report the stop, with your version, on the official Discord.
  3. Check the official announcements for a newer patch before rebuilding anything.
