Garen Q bug [Gameplay]

Garen's q doesn't work on the Nexus all the time. If you use it then attack the enemy Nexus, Garen will just stand there for a few seconds instead of attacking the Nexus. If his q is used as an auto reset then it seems to work fine when attacking the Nexus, its just when you q without it being an auto reset.

To reproduce go in a game as Garen and try to q the enemy nexus if you auto>q the Nexus it should work fine. If you just q it w/o attacking recently then Garen will stand by the Nexus doing nothing for a second or two.
