Several are not working properly or as described at least.

1. If you become fallen champion you unlock achievement of being champion of your new alignment. Well, since char was never crowned at that allignment it is clearly bug.
2. Achiever line is not working properly 37/83 is clearly above 40% - Achiever does not unlock.
3. Avatar of thieves - teleporting out of shop with ~10k priced artifact does not unlock, under current description one would expect it to.
4. Shoprobbing - does not trigger via attacking shopkeeper. I do get that picking stuff, kicking shopkeeper and getting smited in few turns is not achievement worthy, but in case char makes out of shop and out of level with stuff one would think it was successful shop robbery.
5. Scholar unlocks upon drinking literacy potion even if character was literate [reported in another topic, just mentioned for consistency].
