I tried loading up a previous save and the game crashed on me. I got an achievement for it. Suddenly The Dungeon Collapses This achievement is our way of saying "thank you for participating in our voluntary quality assurance program." I love Gaslamp's sense of humor.
Did you read the patch notes? "Fixed: crash that just sort of happened randomly to a bunch of people, but it's fixed now." "Fixed: backwards conditional logic on ranged monster attacks means that monsters were not consistently casting spells; fixing this makes the Dungeon 95.2% nastier." "A lot more filthy, awful tweaking." Good stuff.
