Trial of Chaos bug. Stuck in last boss room.

this is after patch 0.2.0g.

Did a trial of Chaos level 80. In the last boss room which is the flying dragon Uxmal. Instead of following the path down and up the stairs. I just jumped down using Thunder leap. Boss encounter started almost immediately.

Killed him but now it still says enter challenge room and the exit is not opening. I closed the game entered again still stuck. Big bug. Now I cant get my rewards ad the end.
