Spoiler:
After leaving underdark Tashia runs off with Ari, fine, then the dream and cutscene happens fine, the cave is there no trouble, big battle where everyone is slain (including Tashia), cast resurrection on the apparition and
Tashia reappears but says nothing. She is green like ally but behaves more like a summoned creature than a party-member. Cannot talk to her, access record or inventory screens, and she cannot leave cave. Rest and she is still "mind-controlled" (the message I get when i try to talk to her is that she is mind controlled and cannot speak of her own free will.) Cannot drop her from party as she has no portrait, just there like a summoned creature.
Did I do something wrong? was I not to kill Tashia during the fight? Is there some item I need? Could this be because of a "happy patch"?
Please help and thank you.
And BTW, Happy New Year!
