Ok I'm in the counting house in act 3 and went into the counting house and I'm battling a group of enemies that were left after the phony Jaheira and mincs left. Now the problem I'm having is the the enemies keep attacking us, doing damage and going invisible Despite all members in the party have drank an Elixir of see invisibility and Tav having Volo's eye and the potion. Now why have something in the game that don't work and is useless?? Any help on getting through this fight would be appreciated. OR at least let me know if its bugged like the steal the Idol quest in the Druids grove.
