I'm working on a simple particle system program. One puzzling thing that's occurring is that sometimes and randomly my particles( Box()'s) just disappear from the scene (without moving out of Bounds). For instance I may have 30 boxes moving around, and suddenly I'll only have 10, then in the next frame I'll have none. Then I reset the scene and it'll work fine. Then I may reset it again and the same thing will happen again. Any clues?
