Character got stuck in a pillar after killing Arbiter of Divinity - can't progress

Bug Report ID: #1988848341

I was really hoping to get this boss down to get a bunch of atlas passives but I got none and couldn't do anything. Had to log into town and then couldn't access the zone after defeating the boss. After opening the new zone it's just empty - no way for me to get the loot (don't care too much about that right now) and the quest progress.

This is a massive issue for me right now as I was really relying on getting a lot of those atlas passives to keep progressing my character in SSF.
