Steps to Reproduce

  1. Create a prefab building. In my case it’s the Agency including the vault level.
  2. Start a match few times in one session.
  3. End the match.

Expected Result

Building should always restore to state in which I left it before starting a match.

Observed Result

After few tries, building is collapsing in ending screen and stays like that, in the edit mode, leaving behind only indestructible objects and ones that always stay, when you intend to collapse the building.

Additional Notes

I just saved by accident a backup of the island after being destroyed like that… Can I somehow find an older backup?
