[6.6] Garen only moving to opposing spawn through middle lane

I would post this in Bug Reports but I'm not level 7 yet. Bug was encountered on EUW server. This was the first time this bug happened - I have played as Garen before on the EUW server and not had this happen. Throughout all of the game, Garen was consistently moving towards the opposing spawn. I was unable to use my basic attack but could use abilities. Damage could only be dealt using the Judgement ability. Movement could only be stopped by recalling and cancelling. I don't think this glitch can be reproduced. As mentioned above, I have played as Garen on EUW before and it's been fine. I have not tried to recreate this bug as I encountered it at about 22:30.
