[cheat] I can't move

The player on the other side is probably using a cheat. At first, only one of my players could move, and the other ten had their cursors turn white and became unresponsive. Then, seeing that I was stalling, he immediately locked down all 11 of my players—every single one of their cursors turned white and couldn’t move. Why would there be such an outrageous cheat? wtf.
