I can't turn in the "save lemuria in telos" endgame quest. It's the exact same bug that I (and many others) encountered during test realm. I've done 8 runs of this dungeon, defeating the right side last on every run. I've tried disconnecting/reconnecting, re-doing the dungeon & relaunching the wizard101 client, but unfortunately none of those have worked.
So I just did the final boss of lemuria and I didn't get credit and i did it twice didn't flee at all the second time and lived through the entire thing me and a group of friends who were doing it as well didn't get credit for it.
