Um very interesting but major bug between Trundle and Sion

If Sion is ulting and an allied trundle puts up a pillar Sion gets stuck running into the pillar until the end of the ult or he cancels it. I saw it happen one game and everyone thought the game dc'd but the team fight was still going.

All I could think was a very dyslexic Gandalf yelling "YOU SHALL NOT PASS" at his own party.
