Can't stun primed for stun enemies when they perform certain animations.

The indicator above enemies' heads disappears when animations like enraging on some large enemies, burrowing (Dune Lurker), or other any special animations are start to play. At these moments it is impossible to stun primed enemies and often leads to death, because instead of clear screen you achieve that monsters closed the distance and kills you.

Literally again, instead of killing a boss, at the same exact moment boos start to play heave attack animation and instead of killing him I got killed because primed for stun do not work for any animation that isn't idle, default attack or walk/run.
