Ok let's go and name all the npc types
This is how I know them anyhow.


Weapon Clientside
Weapon Serverside
Level NPC Serverside
Level NPC Clientside
Putnpc2 Serverside
Putnpc2 Clientside
Database NPC Serverside
Database NPC Clientside
Control NPC Serverside only
Gani Script Clientside only

All of those seem to behave differently depending on what you wanna do and how you wanna reach them.

And it's important to keep straight which one your using.
