You may have to add more directories to the npc's, as I suspect npcsystem.lua doesn't cover everything.

https://otland.net/threads/error-npc-interface.200135/#post-1925651
Limos was an active member for quite awhile and was very adept with the npc system in general.
She has 4 directories listed. Try using all of them.

You'll want to make sure they are in data/npc/lib/npcsystem/npcsystem.lua

basically your telling the NPC to find npcsystem.lua , which then goes and finds the other 4 directories.

try to use [.code]script here[./code] without the dots, to post your codes.

Did you check if those files exist at those directory locations?

If yes, have you checked if there are additional error's in the console when you attempt to communicate with the npc's?

replace the function near line 558 with
Code: 
    function NpcHandler:isInRange(cid)
        local distance = getDistanceBetween(getCreaturePosition(getNpcCid()), getCreaturePosition(cid)) or -1
        if(distance == -1) then
            return false

        return (distance <= self.talkRadius)
