Random Skarner Freeze Bug
During the last match, I was playing Skarner. The first time it had happened was when I was dueling the enemy Rengar. I would auto attack normally until a few second later; then I would just completely stop. I could cast spells (AoE was spamming on normal CD) but no AA animation or damage would happen.
The 2nd time it happened was when I was farming minions. I would just stop and be unable to continue attacking until I moved my character somewhere else. This bug is very irritating (Not Skarner).
UPDATE: Happened again while trying to help the ADC. I just froze and couldn't do anything until I spammed my move mouse button.
