1. Load save file
2. Open map view
3. Pan directly to the right, find the Easternmost train stop called "Copper Ore Pickup"
4. Click on it- zooming in until you enter 'normal view' or staying zoomed out in 'radar view' makes no difference.
It seems to be this train stop only; other train stops that I tried did not prove to be a problem.
Nothing wacky going on with complex train schedules afaik, there are 40 or so trains with this stop as a potential destination, with a simple 'pick up til full, then drop off elsewhere'.
I have no mods active, although expensive mode is on- which I expect to make no difference
Attached are the .dmp file, current.log, and save file, as well as a screenshot with the location of said train stop.
To any devs reading this: Love you guys. Take care.
