Terrace Map Boss Bug when "stunned/incapacitated/frozen"

Playing ele hit of the spectrum, freeze basically.

Once stunned/frozen the boss, when its time to phase, go into a pool and spawn minions, he just stays there frozen in place, untargettable and stuck.

I know this has been reported with other builds aswell, but i haven't seen a freeze build mentioning this, so sry for multiple post of the same thing already reported i guess >_<

Thanks for your time, have a great day <3
