Some bugs I have encountered while playing with your fixpack:
- Potion of agility description reads it increases constitution (or vice-versa, can't remember) but it works normally
- When being teleported to chess board in Durlag tower, sometimes not all 6 party members are teleported even if they were together in the room where last creature was killed
- After killing Demonkin and returning to Ulgoth's Beard, the cutscene about returning from Werewolf Island is showed again, after which the cultists ambush occur
