[GAMEPLAY] Shyvana - Unable to use mouseclick for 7 minutes

I respawned and coudn't use mouse buttons. Both leftclick and rightclick had no effect. Attackmove (keyboard a) was still working. I reconnected and still had the same problem. Reboot changed nothing either. After 7 minutes mouse clicks were working again like nothing ever happened. While the bug occured I tabbed out of the game to see if the problem was caused by my mouse but it wasn't. Link shows the last fight before the bug appeared.
