Rustbowl boss area bug

Bug Report ID: #3059221130
Playing as a party, we entered the boss area and I got caught on a slight lip, the boss got activated so I am unable to TP out, but I'm too far away to click the arena to enter, so I am stuck until my party can kill the boss.

The game crash every time that I join the map rustbowl.

This is the only map that I never seen the layout. :(
