Issue description

I have a train station with 4 cargo modules in loading mode. There are 2 storages level 3 attached directly to it. The modules are full and there is some items in storages too. When the train with 4 wagon is loaded it takes more goods from one storage than from another one. But it should use evenly both storages.

  • I saw that issue with loose and fluid, I haven't tested with flat items.
  • I saw this issue also when number of modules matches number of wagons (8 modules, 4 large wagons)
  • Only loading trains is problematic, unloading works as expected

I was able to reproduce in sandbox (save attached)

  • The train to load slag is about to come
  • Before loading storages contain 1920 and 2412 items
  • The train is loaded fully (1,920 items)
  • After loading there is 480 and 1932 items left in storages

So one storage lost 1440 items, and another only 480 instead of been emptied equally.

Reproduction steps

  1. Load attached save
  2. Check number of items in storage before loading
  3. Wait until train is loaded
  4. Check number of items in storage after loading
