Train fails to unload all cargo using all available alignments

This is a more complex issue, and generally a lower priority. However, I think it should still be addressed as time permits.

1. Set a train line to deliver a good where the train has a divisible amount of cars, but more than, the unload modules
2. Set the load on the train line to full
3. Set 1/2 of the unload modules to full
4. Release the train to its destination
5. Note that the train will try to unload all cars, but not using all alignments. If it is aligned with a module, but that module becomes full it counts it as a complete unload even though there are still modules it could align with and fill.

again its the crude oil line
save.save

I realize you could set a balancer to strictly even inputs/outputs to help with this, but it won't fully solve it if the inbound cars aren't completely full or something similar happens.

We loaded the save and couldn't reproduce the issue, it all seemed fine.

I think this may have been fixed a few patches ago, sorry that I forgot about it. I'll re-test as well.

Okay, the save file wasn't staged properly to exhibit the reproduction steps. I have properly staged it now and actually the issue does still exist. I got this ticket confused with a different one until I read the reproduction steps.

New save file attached.

Note that the file is a save file, I just added ".zip" as a final file extension so GitHub would let me upload it. Also, I did enable COI Extended's cheats module to speed up playback and because I thought I might have to fill the module manually, but it worked out that I didn't need to do the latter.

save.save

Basically, once one of the two modules becomes full the train still aligns with both modules instead of only aligning to the one that it can fill up, thus causing only about half of the cars to be unloaded.
