Bug when trying to auto then w with darius against yorick's wall.

When i was facing the enemy yorick top lane, i noticed an issue when i got trapped in his walls. it wouldn't always happen, but for some reason when i went to auto his wall, and then use my w for the reset, i would go through the animation, then stop and stand there for a couple of seconds. i couldn't auto the wall again until my w effect had worn off. by then i was already doomed to die because i was trapped. it didn't happen all the time, but it did force me to die several times.
