Kulemak Invitation - Area will not reset

Kulemak Invitation - Area will not reset, boss is permanently dead, even if I bring a new invitation and reset the area from town, reset the checkpoint etc

I am getting the exact same thing. I want to re-do the fight because I died but not I may have to wait 15 minutes for my instances to reset?

Died AFTER the fight, killed him and the room mechanics bugged out and wouldn't stopped, lived for about 15 seconds with 2 Convalesence but lost the drops and the room hasn't reset lol

Same with me as well i cannot reset this fight after the first kill

Same
He died and i died at same time , loot dropped, i came back in to a dea boss but no loot
placed a new invitation in well, fell into well and entered the same room with the same dead boss as before.

Degen killed me a split second after i killed him.

same, they should fix this asap, no reason we should have to wait for instances to reset when we can create new ones ourselves. Way to help people log out lol.
