I think that’s the general problem of the editor scene randomly failing to load (which seems to be a rare godot bug). If you can get the game logs from when that happened that would confirm the problem.
This has been reported before:
I don’t understand why, but sometimes the multicellular stage doesn’t function properly. I can’t edit or place anything in the editor then. It’s strange because this only happens occasionally.
