I've seen this a few times now. There is this small group of Vistani near the docks in Port. They've been getting killed a lot lately. Turns out it's the guards reacting to the bear that is with the vistani. Twice now I've seen the guard charge the bear upon seeing it and proceed to kill the vistani who come to defend the bear. I have a screenshot, if needed, I can send it in a DM
