So, I just started a chanter, because I want to build the laziest party ever 6 chanters. :D
In the starting area I encountered, what feels to me like a HUGE bug.
When I killed the wolves I summoned a phantom when the wolves were down to near deat status and it correctly disappeared after the wolves were slain.
When I got ambushed by the 2 Glanfarthans however, the phantom did not disappear after the fight was over it stayed for the next fight and the fight after with their leader and Heodan.
When the caravan leader uttered his famous "Git inside, run", the phantom did not run, but stayed on the battlefield, so I thought it would surely be gone, now.
NO, once I spawned inside the ruins, there it was again.
edit:
Now, that I quit the save and reloaded, the phantom is finally gone.
