Bugged Monolith Instances, Forced Relog

Hello! Wanted to report a bug I keep having.

Playing were-bear druid. Whenever I am clearing monoliths, I have been encountering bugged instances where creatures would stop spawning and none of my abilities do anything. My character is still able to move freely and sometimes invisible monsters can still hit me but after a while I cannot do anything to progress the instance. The only solution has been to log out and log back in, which results in losing the monolith rewards and having to redo the monolith without rewards. This, as you can imagine, is very frustrating and I am hoping it is fixed soon!

Thanks for reading!
