[Gameplay] Blue buff monster stuck in animation

Didn't get a chance to do a screen cap of it but as Yi, 2-3 times during gameplay I had Q-E'd into the blue buff and if I didn't move, the buff got stuck repeating the attack animation and getting interrupted part way through it - not doing any damaging attack. I had no other buffs on at the time to cause it to be stunned and it did not show a stun animation, just interrupted the attack animation.
