To date, I'm not quite sure how it happened, but on August 4th, 2011, I discoved a serious glitch in Toontown Online parties.
I had just launched out of one of the party cannons. I was in full screen, and I accidentally pressed the return button to minimize the game. When I went back, the game was frozen with me in midair. The sound worked fine, but nothing was happening; it was like a picture. I minimized the game to try to fix the problem, and when I reentered the game, I was in for a surprise.
I was in some sort of black space. I looked down and saw the party, upside down, but still working. I looked up, and saw the hidden moon. I tried to move around, but I was stuck. The sound still worked At this point, scared out of my mind, I closed the game.
The event never happened again. To this day, I have no idea if anyone else has experienced this.
