Trouble unlocking warlock and thief classes!
I'm enjoying the game (rather annoyed that the magic/spellcaster classes take a long time to unlock, but it's okay, I'm patient) and I've completed about 10 scenarios. However, I can't seem to unlock the warlock class. Uncursing items doesn't seem to trigger the achievement and I haven't seen any other type of curse that can be removed. Are there specific options that need to be toggled to be able to have things cursed? Confused.
Also, are gravestones bugged? I can't unlock the thief class, either. I have tried destroying, clicking on, and looting gravestones in every way possible, but it doesn't count towards the achievement.
