I Killed lab 9 boss but instead of dying and get xp for kill and goin to temple. I got stuck in the room and no progress was given. Please help me so I can move forward please. Had screen shot but lost in when signing out of comp to try and make it work.

Thank You

Annoying stuff!

Redoing it should fix it.

Yea went back through and worked the second time around. Im not sure why this happens.

Did you use a Garg Statue to help with the Final boss.

I do recall from the past that unless you or you GC landed the killing blow then it did not count as you completing the quest.
Garg Statues had that effect and hence were not recommended for the Final Lab boss.

Once the boss is dead you can not then wait it out because a boss will not respawn if there is anyone or anything (as in a grave) left in the lab room.

Your only option is to repeat the lab.
