Wait till the first time you answer the door with your Track IR clip on your hat. Or forget to take it off when you go downtown. Good time, good times..........
Do not gloss this over. I can't stress enough. over 16 in a 400+ unit mission will cause warping. If you go over 400 units then the number in you can host and have stability goes down to 14. Pings will also be important to watch to avoid warping and silliness.
