Mob activation failure in temple

Golem works(primarily) mobs that need to be activated bug out constantly. I either have to sit there for 30sec - 1min or exit to character select to and re-enter to activate them.

My bet is on Ambush mod(teleport) on Headhunter messing up the activation. Maybe orb of storms since it seems to make the undead reaper dudes bug out in their crow form.
