Relic Chimera fight is horribly broken and now I have to wait 20 minutes to leave...

Hi, I have just killed Chimera with 7 others. After killing the boss nothing happened, the duty did not end and we did not get our reward. What we have received however is a lovely 20 minute wait, as the only ways to exit this duty are to die, kill it (theoretically) or to run out of time.

This is an appalling bug, how did this not get picked up before now!?

Does this mean after wasting 20 minutes I'll have to find another group to try again? No wonder no one wants to do it if this is the reward!

I was in this group, killed chimera, and no exit, no update. :(
