triggeraction doesnt work second time

[Stryke]

Control-NPC:

PHP Code:

function onPlayerLogOut(pl)
{
  if(pl.client.RideStatus == 1)
  {
    pl.client.CurrentRide.destroy();
    triggerserver("weapon","-System/Main","boardstay",pl);
  }
} 


-System/Main Weapon:

PHP Code:

function onActionServerSide(id)
{
  switch(id)
  {
    case "boardstay":
      temp.pl = params[1];
      temp.r = putnpc2(temp.pl.x,temp.pl.y,"join(\"object_rideitem\");");
      temp.r.owner = temp.pl.account;
      temp.r.ani = "silence_woodenboardidle2";
      temp.pl.client.CurrentRide = temp.r;
    break;
  }
} 


It gave me a error trying to use the "putnpc2" command in the Control-NPC, so I tried to get around it by making the Control-NPC send a triggerserver to another Weapon, in this case (-System/Main). However, it is never received. (Checked with echo multiple times). How would I get around this?

I need this because I don't want the skateboard to disappear after the player logs out while is on the skateboard.

triggerserver gives an error too.
