Trundle glitch

Played Trundle yesterday.

Start hitting a target , then Q, and about half the time he would stop attacking and just stand there.

But not with any pattern.

Didn't matter if it was a champ or a monster.

AA enabled.

Never did this before.

update:

Just played Trundle again and it is almost every time now, VERY ANNOYING!

It is really bad in a team fight with lots of targets all over each other. If this is not fixed, I just wont play Trundle anymore.

It looks like his Q is being applied to him.

And I posted this in gameplay to see IF it was a bug.
