Saw that I still had the quest to kill Zekvir on my shaman, figured I’d go bang that one out quick this morning.
Successfully killed him and received credit for the quest. But the actual delve did not complete, acted like I hadn’t killed Zekvir. The loot room did not open.
Since there wasn’t anything further to do I left. I got the quest credit anyway, but still… Thought it was odd that the delve didn’t complete/finish when I killed Zekvir. So here’s another bug report to add to the 11.1 pile.
