The game crashes when you deconstruct an overheat-broken sweepy dock.
TL;DR: I found out that sweepy apparently has to be in the state when it has no power left and constantly knocks on the dock. Deconstructing a dock where no sweepy has spawned yet or where sweepy is still able to roam around does not crash the game.
I was able to reproduce the crash on my test-world after i repaired the original dock in my current play-through.
I tested three situations in the provided save file:
- The left dock has sweepy in it's "empty" state when it constantly knocks on the dock. Deconstructing this dock crashes the game.
- The middle dock has no sweepy spawned yet. No crash when deconstructing.
- The right dock was overheated recently and it's sweepy still roams around. No crash when deconstructing immediately. When you wait for this sweepy to be empty (~300s), deconstructing this dock will crash the game too.
- overheat the sweepy dock
- wait until sweepy stops roaming and stays at the dock
- deconstruct the dock
