Oh... duh lmao! Yeh I had him in my party. He sometimes freaks out like Arhu unexpectedly and starts attacking my party. This mostly happens if a trap is set off causing burning damage.
Yeah, this friendly fire reaction is way too easy to trigger. Typically, i set the ground on fire, the fight ends, one of my guys runs over the fire, gets a bit angry, runs over the fire some more and is now angry enough to attack me. I think environmental damage shouldn't trigger this reaction, at all.
