Entered in a fight with Madora on my side (North Cyseal - First Woods) Some zombie goats, one undead archer and an undead mage. I should have died with the last arrow but resurrected automatically and died with the next arrow, ten times. Finally, the archer missed me. Then, the character could damage ennemies but ennemies acted like they hit me but didn't do damages.
Sorry for my poor English, I could explain it in French if you prefer.
I had the same issue in a fight, but with my only two base chars. Scarlett rezzed a lot of time Under undead archer fire, and then she became unkillable. Maube she became unkillable when I entered another fight, while the first one was not over yet.
