Bug description: As the title says, after defeating Hymdall in HoV the walls disappeared only to reappear several seconds later. I do not know what caused the bug (we did not get into combat shortly after; maybe DoTs still on the boss? however I have done it many times with DoT classes and did not encounter this bug at all, also no classes with pets nor companion pets).
Proof: https://i.imgur.com/o2erx7K.jpg You can see on the right clearly Hymdall's boss frame which is proof for defeating him (also the chat log from M+ addon).

Happened to me too, posted a few days ago, in my case it got in combat with a companion. but I also heard shadow priests have this problem with those tentacles, they keep attacking the boss after you defeat him.
