Sigma animation bug

I was just playing comp on Hanamura and i used my kinetic grasp as sigma but i got cancelled by rock and what proceeded was him stuck in the “suck” animation with his left hand open and out but the black void part that is normally there was gone.
it didnt affect anything but you couldn’t see his right hand. you could still shoot though. oh and even after death it persisted
so nothing big but it is still a bug
