What were you doing before bug occurred: Going through King Calvus Cutscene, a random player helped me during the battle earlier
Steps to reproduce: No clue. Maybe it has to do with the boss respawning? It looks like the game is trying to stop it from rendering or something, with how it flashes in and out.
