Pixelmon Mod

I am starting a new world on singleplayer on the Crew adventure map.. This map has NPCs that are included with it and the first time I launch the map, they are there and you can talk to them... After about five minutes, every NPC disappears. Please help. Im using the technic launcher to play pixelmon

Pixelmon does not support the technic launcher, the problem that you have may be caused by this.
Try running pixelmon without using the technic launcher.

Actually, technic does not support Pixelmon (or any mods), which is why it doesn't work
