I built a 30x30 particle accelerator in my singleplayer voltz world. It gets to 100%, makes the deep "boom" noise, and it goes back to 0 again. The problem is, it is not generating any antimatter. I'm putting in empty cells, and have tried 120, 240, AND 480 volts. It just won't generate any antimatter. Any ideas? Help would be greatly appreciated! Thanks!
