For some reason, at certain random times, in the plain old version, the health, temp., exp., and food bars at the bottom get all screwed up (i.e. bars half gone, sliced up, etc.) It still has the value, so it doesn't screw up the gameplay, but I just wanted to bring it to attention,
-edit, actually, it stops when you reload the saved game, so it doesn't really matter. But i found another bug where items (corpses, firewood, robot wreckage, etc) cannot be picked up on the edges of the maps.
