Good point. But, no, I couldn't possibly be calling ClearWorld in the middle of the update game loop, or the game would stop pretty quick, lol. It's only happened once in the month or so that I've had Particle Candy fully implemented in the game, which is what makes me think it's a PC bug rather than a bug in my code. If it was a bug in my code, I would have expected it to turn up at least slightly more often.
