Attack speed debuff ?!?

When i was playing the game today , and i opened "Muli the evil twin" to feed him some potions , i randomly swiped left and i saw that he had -9833.6% attack speed/cooldown which meant he would attack once every 60 seconds , i would be happy to post the screenshots i have , but i dont know how :P

He's on a hangover. Wait five seconds and check again.

Didnt change the whole game ...
