[BUG REPORT] Nocturne's Q is bugging in the last couple of days, details inside

When I was playing on my main account in EUNE, I noticed that sometimes even when I stand on the Duskbringer trail I don't get the AD and movement speed buff, and that sometimes when I cast the Q while moving the trail is being casted ahead of me instead of beneath me, in a way that forces me to move for a little bit just to get the buff. This bug has been ruining my ganks and jungle clear when I play him yesterday.

It only started happening since last patch, or maybe the last couple of days, I belive.

Can any Rioter comment on this? I really want to be able to play my favorite champion again without worrying about this bug anymore. :<

Thanks!

BTW, I'm sorry for posting this here, but I cannot access the NA Bug Report forums because this account isn't level 5 yet. I'm posting this here because Rioters don't pay any attention to the EU forums at all.
