Isn't there a problem with npchandler

in npchandler.lua. Replace this function.

Code: 
function NpcHandler:isInRange(cid)
        local distance = getDistanceBetween(getCreaturePosition(getNpcCid()), getCreaturePosition(cid))
        if(distance == -1) then
            return false
        end

        return (distance <= self.talkRadius)
    end

So something like this
-- Returns true if cid is within the talkRadius of this npc.
function NpcHandler:isInRange(cid)
local distance = getDistanceBetween(getCreaturePosition(getNpcCid()), getCreaturePosition(cid))
if(distance == -1) then
return false
end

return (distance <= self.talkRadius)
end
local distance = getDistanceTo(cid) or -1
if(distance == -1) then
return false
end
Click to expand...

plus do i have to restart the server?

Reload the NPCs after you have replaced the function NpcHandler:isInRange(cid).

Code: 
[COLOR=#333333]-- Returns true if cid is within the talkRadius of this npc.[/COLOR]
function NpcHandler:isInRange(cid)
        local distance = getDistanceBetween(getCreaturePosition(getNpcCid()), getCreaturePosition(cid))
        if(distance == -1) then
            return false
        end
 
        return (distance <= self.talkRadius)
    end
