Kept making me walk in a straight line (Video Proof)

Just watch the vid and see what happens. Basically, If your too lazy. The bug is that no matter where I click, I continuously walk in a straight line. Having no control over my movements. Then I tried to reconnect but the game would not let me. It just said "You have lost internet connection, Please try to Reconnect again. I tried to reconnect over and over again but still no progress. I wish that this bug be fixed and also for me not to get banned for this annoying bug. Link : http://youtu.be/DW4hptyoxuk
