[2.0.15] Blueprinted train schedules don't stick if the first cargo wagon is built last

[jmcgee1125]

What did you do?

I have a blueprint of a 1-4 train with a schedule already set. When bots build this train, they sometimes place the last cargo wagons before the first. When this happens, the schedule is forgotten. I can replicate consistently by disabling construction bots then building the locomotive first then the cargo wagons from back to front.

This also works for 1-2 trains (build locomotive, last wagon, then first wagon).

Here's a video of me building the train that breaks. Fuel requests don't make a difference.

What happened?

The train retains its schedule up until the first cargo wagon is built, when it forgets it.

What did you expect to happen instead?

I expect the train retains its schedule when the blueprint is completed.

Does it happen always, once, or sometimes?

Always occurs so long as the train is built in this order.
