I cannot interact with the ashes of Livanio Deltorius in the Brutal Arena section of Ashbound Hall. The quest arrow is stuck on Sirilonwe "reacting" to his attack even after killing him and telling me to search his ashes. When I leave to the next room and come back he respawns so I tried all of his dialogue options but the bug remains. Logging out doesn't help either.
I reported the bug in game (ticket 251115-003008) when I noticed other players around me didn't have any issues with the quest. Maybe it's worth noting that I had issues interacting with Livanio Deltorius when I first got to this stage of the quest as well - he was there but there was no quest marker on him or way to talk to him.
