Custom logic error - why not item flows to downstream?

Process Finish Trigger with Custom Code is applied to Processor1 and Processor5.
Why aren't items flowing from the two queues to the processor?
Another question is why item is not animating in Processor4.
Thank you in advance.

Because you destroy the item in the Process Finish trigger it never 'properly' exits the processor, breaking the internal logic of the object. You could first remove the item from the processor using "moveobject()" and then destroy it to fix this.

But what I would recommend is to set up a second shape frame for the item in the Flow Item Bin, so the item can be switched between the two visuals at will.

And instead of the processor use a separator that splits the item into three copies and sends them to the downstream processors as normal. In the Process Finish trigger you would then just switch the frame of the item (and possibly adjust the size).
