Quasii

I can not change group members any more. It first startet when I tryed to take Hirvas in my Party. He aggried but didn´t show up ore left his place in the countryside. later I tried a view times to change him to my group without result. Now I can not change anyone. sometimes I can dismiss Members with Effekt. Mostly even dismissing does not work. maybe same reason? I can´t enter second flor in "Leuchthöhle" (Caed Nua) Please give me some hint. Quasii
