I've gotten a bug a couple times where it crashes when I try to descend into one of the new Aslona areas. Twice with the tower, and once with the goblin place. Fungal caves have never had this issue

Player can't be found anywhere! Try to restore a backup if available.
Sadly the save files don't work at all anymore, it crashes immediately when I load the save (presumably it entered the new area, and autosaved there)
