Champs seem to be recovering before stun ends
This has been happening in all modes of the game with an aggressive AI
I am playing on an iPad pro (10.5 inch) and champs seem to recover before the stun indicator ends. I have also experienced ghost being hit before invisibility ends, but have not been able to reproduce it consistently.
I have a video of my fighting against emma frost (boss) in mutant treasure island quest, but do not know how to upload.
