Crane Resources misalign on lists after about 40 hours simulating.

Hello,

I am having a problem with crane resources being pushed and pulled from lists. I only have 5 cranes in this section of the model. After some time, it says I have 5 cranes free but then 2 entries waiting to be pulled from the Used cranes list. However there is no puller tokens to pull the used cranes. Any idea what I'm doing wrong. The model is saved at google drive link: https://drive.google.com/a/ualr.edu/file/d/0B3ZuAXNcdE9CM1U1cXYyQnFiUm8/view?usp=sharing

The green number represents how many you have of that object in the given activity. So for resources the green 5 represents how many you've acquired. On lists the green number represents how many items are on the list

In your logic you have 5 tokens it looks like, so you first acquire 5 resources, and then after assigning labels you push those 5 to a list. So it looks accurate to me.

Yes you are right, but I have 2 in the used craned list.

So the way it flows, in the flow on the left a token pushes the crane to the free cranes list. Then another object (in a different process flow) pulls the crane for use. So the token in the flow on the left moves to "pull from used cranes" list. So whenever the object is done using the crane it pushes to the "used cranes" list. So It is right to show 5 free cranes but there shouldn't be 2 cranes on the "used cranes" list.

I'd have to see the model where it is pushing the "used" cranes onto the list... Because the process flow in the PNG appears to be doing what it should. But like I said I don't know where the "used" cranes are getting pushed onto the list (You didn't show that part,) So I can't say where/how that might be getting mixed up.
