Biter eggs, and possibly other spoilable items seem to not behave correctly between saves.
I noticed that my chests were being destroyed by biters. I immediately loaded a save that was made 5 minutes prior. I thought that I had 5 minutes to remove the eggs or set up some turrets. However, I was surprised to see that I barely had 10 seconds to react before the biters spawned. I tried to load an even older save - 10 minutes before. Again, the biters spawned as soon as I loaded.
I attached the two save files. I paused them in the editor as soon as I loaded. The biters are already hatched, but there should be more eggs in the chests. I am sure that these are the original biters - I have no defenses, so they destroy everything after appearing.

Welp, I deleted the saves and could not replicate the bug when I tried to just now. Here are the logs in case they could somehow still be useful. I will continue trying to replicate it and will post an update if I get it.
