I have the same crash! Ice-E fans are borked. The thing is the crashes didn't start happening until late-game. I had Ice-E Fans going for hundreds of cycles without issue. Maybe the issue is specific to the one dupe Burt, or maybe it's specific to my one Ice-E Fan that's set up behind an Atmo Suit checkpoint. Still experimenting to find out. EDIT: The crashes were specific to the Ice-E Fan behind the Atmo Suit Checkpoint.
Same issue. I have been growing this Arbor Tree since God knows when, it NEVER drops an acorn even though it says 10%. People on reddit are saying I have to uproot and hope a second acorn comes out? What the heck? This is bugged or mislabeled.
