Custom class emitter wont delete

I have a problem with a custom class emitter I have called Graphemitter.
Usually it works fine, but on my latest emitter datablocks the emitter is not deleted, and I can't delete it from the world editor because it's id is 0.
Made a video which shows the problem:




I had this problem once before, but then i fixed it in the code. At that time i had an error message to work with, this time I get nothing.
The delete function is called properly and the emitter calls onRemove aswell.

A working emitter

%flame = new GraphEmitterNode(){
      position = %pos;
      rotation = "1 0 0 0";
      scale = "1 1 1 1";
      dataBlock = flameSpiralSpellNode;
      emitter = g_sampleEmitter;
      velocity = 1;
      standAloneEmitter = 1;
};
 /*...*/
datablock GraphEmitterNodeData(flameSpiralNode : g_downSpiralNode){};
datablock GraphEmitterNodeData(flameSpiralSpellNode : g_downSpiralNode){ };
datablock GraphEmitterNodeData(spellWave : g_wavesNode){ Loop = false; };
 
function flameSpiralNode::onBoundaryLimit(%this, %node, %Max)
{
   if(%Max)
      %node.Reverse = true;
   else
      %node.Reverse = false;
}
 
function flameSpiralSpellNode::onBoundaryLimit(%this, %node, %Max)
{
   echo("node Datablock should change now!");
   if(!%Max)
   {
      echo("node Datablock should change now!");
      %node.setDatablock(spellWave);
   }
}
 
function spellWave::onBoundaryLimit(%this, %node, %Max)
{
   if(%Max)
   {
      %node.delete();
   }
}

Bugged emitter

%newEmitter = new GraphEmitterNode(){
      position = %pos;
      rotation = "1 0 0 0";
      scale = "1 1 1 1";
      dataBlock = advSp_1;
      emitter = g_burnerEmitter;
      velocity = 1;
      standAloneEmitter = 1;
      xVar1r = 2;
      yVar1r = 2;
      xVar2o = 1;
      yVar2o = 1;
      zVar1h = 0;
   };
       
   %p1 = MyTweenEngine.to(1000, %newEmitter, "xVar1r:0, yVar1r:0, zVar1h:2.5, xVar2o:10, yVar2o:10", "ease:circ_out", %this@".stageTwo("@%newEmitter@");");
    
   %p1.play();
/* ... */
datablock GraphEmitterNodeData(adv_splash : g_wavesNode){ Loop = false; };
 
function voidSphere::stageTwo(%this, %emitter)
{
   %p2 = MyTweenEngine.to(500, %emitter, "zVar1h:0", "ease:circ_in", %this@".stageThree("@%emitter@");");
   %p2.play();
}
 
function voidSphere::stageThree(%this, %emitter)
{
   %emitter.setDataBlock(adv_splash);
   //%p2 = MyTweenEngine.to(1000, %emitter, "zVar1h:0", "", %this@".stageThree("@%emitter@");");
   //%p2.play();
}
 
function adv_splash::onBoundaryLimit(%this, %node, %Max)
{
   if(%Max)
   {
      MyTweenEngine.deleteAllFor(%node);
      %node.delete();
   }
}

I have wondered if it is the Twillex resource that does it, but i can't imagine how.
