solves warning 213: tag mismatch: expected tag "t_WEAPON", but found none ("_")

I also noticed there's still a_npc.inc with such a stub:
#error open.mp doesn't yet support NPC scripts

Maybe somehow change this to be a wrapper over the new npc include file?

UPD: Oh, seems like we really don't support specifically NPC scripts like it is for vanilla SA-MP NPCs (laying in npcmodes folder and using a_npc), or do we? Does FCNPC support this as well?

[AmyrAhmady]

no we don't support them, nor does FCNPC, because they run in another isolated environment in samp-npc (samp-npc has its own pawn vm and runs the script in there)

Oh that's really interesting. So maybe deprecate them instead of the current message like "it's not supported yet"
