[2.0.21] Train reports no path to target if all target stations are filled

[Premu]

My train system on Nauvis consists of general purpose trains which will drive to any loading station if they are empty and chose a target station based on their content. I have stations for iron ore, iron plates, copper ore, stone, coal, rocket fuel and uranium.

In case the trains are fully loaded, but the limits at all target stations are filled out, they show the "zzz" sign which is expected.

The exception are those waiting at my two iron ore loading stations. If all of the three potential unloading spots are fully satisfied by trains already, they insist to report "no path". Should one of the stations get free again, the trains will drive their immediately, so it's not really a game breaking bug. It's just that the message is irritating. I don't really know why the interrupt for iron ore is somehow handled differently than for any other material.

This screenshot shows one train and its schedule. Most interrupts are basically carbon copies of each other, only the target stations are different. The savegame is attached.

You have 1 station that is unaccesible that is causing the no path to be shown,
I recommend setting that station to a limit of 0 to surpress the no-path

Since its working as intended, I will move this to not a bug

Ah, thanks - the bane of copying something in preparation and forgetting it.
