[GAMEPLAY] Auto attacks replaced with other skills.

So I just entered a game, and when it came to auto attacking minions or a champion, my auto attacks were replaced with Lissandra's Q (Ice Shard) and this would happen consistently. Though when I attack a tower/inhib/nexus it changed back to a normal auto attack, but sometimes changed back to Q and there would be no damage to the structure. Sometimes this effect would visually go backwards and in all kinds of directions.

My entire team also encountered this problem, where Lulu's auto attack was replaced with Q (Glitterlance) while Fiora's auto attacks were replaced with her ult.

This only happened this one game that I've played so far. One of the people on the other team recorded it so it'll surface soon enough~
