[1.1.110] bad train state by paused game interactions?

[Icicubes]

If you look in my provided save file at the closest train and click on its menu it states it is in automatic but it doesn't do anything. The train schedule GUI displays that it should be in automatic and going to the station but there is no path drawn. If you turn it to manual and back to automatic it starts going to its station as it is supposed to do.

Right before I noticed the bug, I was mentally confirming/testing my circuit network train station design that prevents any (≥2) unequally sized trains in the same time frame to travel to the same station (that is consisting of multiple train stops, one for each train length, a multiple of 2 wagons), by prioritizing the largest one via disabling all lower (train length) train stops and 0 Limiting all higher train stops. To test this simply set up 2 trains, pause the game, turn the 2 into automatic and let them drive to 2 different train stops of the same station.
