NPC only shows after "update level"

Classes have loading issues on the client-side, just join them on the serverside and use an attr variable. I.e:

PHP Code:

function onCreated() { 
  this.windowtype="1b"; 
  this.join("window"); 
} 


PHP Code:

function onCreated() {
  this.attr[1] = this.windowtype;
}

//#CLIENTSIDE
function onCreated() { 
  this.setShape(1, 32, 32); 
  showimg(200, "sorna_window"@this.attr[1]@"_glass.png", this.x, this.y); 
  changeimgcolors(200, 1, 1, 1, 0.7); 
  changeimgvis(200, 0); 
  showimg(201, "sorna_window"@this.attr[1]@"_frame.png", this.x, this.y); 
  changeimgvis(201, 1); 
}
