Uberelder bugged with maven

this happened to me two times this league now

fight is over, zana comes, uber elder wont disappear and maven is still yapping. No drops,no achievement. it is a lot of effort and currency for this fight for me so i am pretty pissed.

ofc i could have toggled maven off- but that was by accident and i think everybody could agree that this cant happen!

Sounds like a bug. Probably need to report it as bugged on that section. I see a few similar posts but haven't found a big one yet. Can understand the frustration.

Certainly can see some others saying they have encountered it during the event. Unsure wat the cause is. Some suggesting it may be to do with grafts, or area modifiers that are causing some problems with a few things.
