Recently, my client has been recently been acting weird. For instance, my client would just stay in a black screen when I attempt to do a level. I disconnect after a few minutes, then my client works smoothly. Also, I sometimes encounter a weird bug where everyone goes off boundries (clockworks: everyone just walks off the track). My internet was working fine, and no, it wasn't lag. I encountered that problem when I played lockdown. After a few minutes, I haven't disconnected from the server at all. I was still in the lobby. So I had to log off.

This problem occurs about every week or so.
