I was playing Blockland the other day, and all of a sudden a black ring circled aroud my screen, only leaving a round hole left on my screen, and when I moved my cursor, it just created more cursors i it's trail, and when someone typed something, I saw multpile copies of it. Apperently, this has also happened to some of the people in the RTB chatroom. It only happened once, but i'm curious to find out WHY it happened. Any answers?
