a lot of people have probably noticed this. when you make a photon laser using pcln, the laser is perfect and all that... but when you load it again from a save, the laser that is fired by the pcln is inconsistent-with many gaps in it.....
This actually has to do with the number of particles on the screen. The behavior of PCLN changes when producing photons depending on how much material is in the save at any present moment. :(
