Arbiter arena bug

Ref ID: 3142657243

After killing the Arbiter and leaving the arena via portal then coming back it's possible to walk on the bridge that connects the platform to the elevator that we use before the fight to get to the arena, the bridge will be invisible and the Arbiter's first voice line will be played again.

Screenshot for reference:


Edit: One thing I forgot to mention but that might maybe help identify the cause of this issue is that I left the arena after killing the Arbiter to trade an item, naturally another player joined my party while I was in my hideout and only after the trade was finished and they left the party I went back to the arena to finish grabbing the loot and then I witnessed the bug. Hope this helps!
