[GAMEPLAY] Cassiopeia receives movement and attack commands not issued by the player.

Cassiopeia will receive movement commands and attack commands that are not issued by the player when Cassiopeia uses Twin Fang after stopping on any map, regardless of circumstances of its usage.

Cassiopeia also receives attack commands from this: http://i.imgur.com/2laLqtY.png

The bug occurs on Summoner's Rift, Twisted Treeline and Howling Abyss and in Nexus Siege, and Cassiopeia seeks to travel to the top right corner of the map regardless of the side Cassiopeia's team is on. http://i.imgur.com/NXKujNL.png http://i.imgur.com/8Pq72Bf.png http://i.imgur.com/qXU5Ckl.png

This bug occurs regardless of items, runes, and masteries, or lack thereof, and equally with all Summoner Spells. Target type of the spell has no effect on the bug; bug occurs when Twin Fang is used on minions, champions, and on all monster camps. Although the bug causes involuntary movement to one side of the map, there appears to be no difference in the bug's behaviour between loading into game as either Blue or Purple team. Bug can be consistently reproduced but I have no clues as to the difference in circumstances that cause some commands to be attack rather than movement alone.

To reproduce:

1. Pick Cassiopeia into a game (No difference between game modes I have been able to test.)
2. Level Twin Fang.
3. Issue a Player Hold Position or Player Stop Position movement command.
4. Cast Twin Fang on a valid target
