for me npc's are working fine in 0.3b R2 version.

Make sure:
-> There is nothing that may interfear with the NPC to spawn such as Dialogs and stuff.
-> put this code in some callbacks that the NPC would need to use

under the callbacks:
OnPlayerSpawn
OnPlayerConnect
OnPlayerRequestClass
OnPlayerRequestSpawn

Код:

  if(IsPlayerNPC(playerid)) return 1;
