Instance lock after killing Olroth

It seems to be a consistent thing that is happening. Once you go to a map that contains the boss and if you manage to one shot the boss, he skips his second phase and just dies there leaving you locked in the room unable to exit/tp out.

Sadly, I haven't found a way to reset it and the only thing that works for me is to simple log out for a few hours. I am not sure if this follows the usual 8-15 mins reset timer, but even if it does, I think this would still be kind of annoying.

What I assume is happening is that the instance itself is linked to the second phase of the boss, so no second phase = instance not done!?

Edit:

Seems like there are more cases like this:

Edit#2:

Logging in after 20 mins and I was in my hideout, so assuming it is following the 8-15 mins rule, seems to be correct.
