NPC Synchronisation Error

[ffcmike]

Lets say I have the following NPC with the script:

PHP Code:

function onCreated(){
  this.setimg("something.png");
  this.setshape(1, 32, 32);
  this.level.flag = this;
}

function onPlayerTouchsMe(){
  this.hide();
} 


This correctly hides the NPC to all players within the level.

If a player were to then reconnect, or log in to the same level, they would then see the flag is visible even though on serverside it is invisible.

Trying:

PHP Code:

echo(findplayer("ffcmike").level.flag.visible); 


Echo'd 'false'.

Edit - Actually turns out that I had the setimg(); occurring Clientside, and this is setting the NPC back to visible on the client. So it's quite easy to fix but still a slightly odd behaviour.
