In this project: http://scratch.mit.edu/projects/13408071/, the sprites can fire bullets. I want it to be so that when two bullets hit each other, they both delete themselves. This works sometimes. But sometimes only one of the bullets gets deleted, which I do not want to happen. Does anyone know how to make it so that they always both get deleted?

Usually because there is not enough time for the other clone to detect it before it is deleted. I notice you have wait 0.0001 seconds which is far too short try 0.1 in both waits and see if that fixes it.
