dredknightUsually the game prevents the player from converting if the amount of faction native castles has reached the maximum capacity.
Maximum converting capacity is defined in MMH55-settings.pak
Just to be sure that reanimation patcher is working - when you go to a Witch hut with a hero, are you asked a question to pick a skill OR you are given a skill immediately?
Maybe there is another Dungeon AI running somewhere out in the fog of war and thus not letting me rebuild. Will find out later on.
Witches are always asking and offering two skills if available, so this part is fine. I created another map and patched with MapMixer - same result for Consume Corpse not working as it should be.
