I was playing Grim Gallery with my Kat, then, after I used the Light Ray ability, the Kat kept on using it for no reason after the cooldown for the rest of the level. Just to make sure, I stood still, Put my hands away from my Keyboard, waited for my abilities to cooldown 4 times, and saw my kat using the ability on its own 4 times. This is a very annoying bug and I highly recommend that you fix it as fast as possible.
