I started displacing LTN with this mod when I noticed the following scenario:
1. Request 2000 items
2. If the loading station puts in 2013 items then the train does not go to its requested destination unless those 13 items are removed, which is fairly easy to do except for scenarios when there is a timing issue with adding and removing the overflow items and it misses exactly 2000.
When I'm not doing compound deliveries, I don't care about the overflow items since another train will be dispatched when the request threshold is reached. I would suggest adding the ability to request >= 2000 items for scenarios like this unless I'm missing something when is comes to handling this.
