Gnar Bug?

I keep getting this bug like 3x a game and its the absolute worst... I THINK it occurs when i use W in Mega Gnar right as a turn back into mini gnar(W is an actual activatable ability in mega, but just a passive in mini), but whatever it is, my mouse in game is perma stuck as a blue diamond targeting mouse, and i cant do anything that requires left clicking... I cant click on the minimap to move my screen across the map, i cant ping, and im pretty sure i cant even use other abilities if i dont have smart cast on. This stays that way till i get back into Mega Gnar and use the ability again.
