Bellus Undercroft

Im currently having this issue for 2 days. Support cant seem to fix the issue. It stops temporarily when I detach the bridge and only happened in firestorm. Now its happening in the official viewer too. I even had the region owners come and look, they found nothing. 2 region restarts hasnt resolved this. Setting myself to a defualt avatar has not resolved this. Im not sure what else I can do.
