I cleared out level 4 of the game, decided to see what the wizardlands were all about. Went through the dimension door from my pocket dimension, and upon stomping a diggle to death, the game froze. Pretty disappointing
Perhaps, where are the save files stored? It seems I was lucky enough to have the game autosave just before entering the dimension. Unfortunately, it is now telling me that the dimension can only be entered once per character, despite the fact that the game crashed while in the dimension, and the save is from a time before actually entering the dimension. I'm guessing the devs can edit the save so that they can re-enter the dimension.
update: what the hell? My saved game has disappeared entirely. I cannot resume the game now. Just fantastic.
Delete the documents/gaslamp games/ folder, then run the game with the "-nukesteamcloud" parameter (in Steam launch options, or through a shortcut) once, see if issues persist.
