Train will not load if the more wagons then station

Issue description

I have a train with 1 diesel loco, 1 fluid wagon, then 8 loose wagons. If I try to load that train at a station with 1 stop, a fluid module, and 4 loose modules with a train schedule set to require full of iron ore, the train will not load the last 4 wagons.

Reproduction steps

1. Create train with 1 diesel loco, 1 fluid wagon, then 8 loose wagons
2. Create a station with 1 train stop, 1 fluid export and 4 loose imports of iron ore
3. Create a train schedule that requires the the stop to have full cargo of iron ore before it can leave.

Train will never leave and never fill up the last 4 wagons.

Expected Result:
Train would load all 8 wagons.

Work around:
You can set the stop to have no leave conditions and then it fills up all 8 cars correctly

Don't know how the game actually works, but it's almost like the train is behaving that it can't move past the train stop if the condition isn't met, rather than moving as far as it needs to fill up the train.

No save file is attached, but the issue is most likely fixed, as we reworked the alignment logic significantly since this bug was reported.
