just realised that you cant get multiple achievements at once. you get your first achievement that you unlocked, and when its time to get your reward for the second one, your game just crashes and it shows the black screen and i need to reload it again. the worst thing is, after reloading the game, you wont get the souls that you SHOULD get after completing that achievement.
hate when you kill a boss on stage 19 (nightmare stage 9) and then when the boss is dying he cast a spell that stuns and make the floor below you all greeny and stuff and you just get stuck forever and the exit door is just next to you.-.-. yes, that just happened to me
Glad you found Auto-progression in either the Settings menu or by pressing "G." =)
