I was getting this bug the other night except much worse, I couldn't see myself, team mates, boss, mind traps, lightning balls, or platforms at all just name frames that's it. Every now and then some things would re appear and then vanish again. Tried changing graphic/camera options and re-logging to an alt to fix it nothing worked. As soon as I got into the instance random things start disappearing. Also it wasn't just happening in SOA's room as the bridge near the pylons would disappear when running back. At first I just lol'd and thought hmm "challenge accepted". However not being able to see where mind traps are as DPS is not very beneficial to my team.
