I was playing Carnage Galore a while back, and I ran around the first hub's maps for a while (in nightmare, mind you) looking for a third of the puzzle I could not find. Since I was using the mage, the instinct of backing up my savegame came from Kmod, but I disregarded it. Upon pressing the damned switch, I got attacked and killed, so I tapped the F9 button... yes, I do want to quicksave, well no, can't find file hex609.hxs.
Fearing the worst, I ran it again, and behold, my savegame is corrupted. I find it interesting how it only happens with the mage. Just out of curiosity, has anyone else had this annoying problem with Doomsday (or, at least, the versions used in these mods)?
