Combined supply chains work, but are sometimes displayed incorrectly.

In my current game, I have a fairly complex supply chain (err, “complex” for TF standards) to a steel mill, with trains and trucks in several stages:

The blue line is a train serving coal to the transfer station (Church Stetton West, at the lake).

The light green line is a train serving iron to the transfer station, and transporting goods back to the iron mine, where they are picked up by trucks and served to the city (Church Stetton, bottom right).

The dark green line (bit hard to see) is a truck line from the transfer station up the hill to the steel mill (Oundle East station, top centre/left). The trucks clearly pick up coal from the transfer station and deliver goods back down.

Everything works – trains deliver coal and iron, trucks haul them up the hill, pick up goods and drop them at the transfer station, from where the iron train, on its way back, transports them to the iron mine, where trucks pick them up and take them to their final destination. The lines make money (mostly…), iron, coal, and goods are produced, and transported. After setting up, it takes a few years until the game realises what’s going on, but then, it’s fine.

There’s one bug in there, though:

The iron supply chain is not displayed correctly. Iron waits at the mine, my train gets loaded with iron, and delivers it to the transfer station, where I get payed for it. At that point, however, the iron disappears.There is another iron mine somewhere left of the steel mill (not on screen), which automatically delivers iron to the steel mill.

Now, either the steel mill gets all its iron from the automatic delivery, then why is “my” iron mine producing? And why do I get paid for delivering it to a station in the middle of nowhere?

Or my iron eventually gets to the steel mill and is processed, then why don’t I see it delivered there, as I clearly do with the coal that is transported over the exact same two stages?

That’s not an issue with combined lines, though:

This is a pure truck chain, no trains involved.

Iron is taken from the mine (upper left) to the coal mine (lower left/centre), while coal and iron are supposed to be delivered to the steel mill (right edge of the screen). While again, the chain as a whole works and every industry involved is producing, the iron disappears somehow at the transfer station (the coal mine). It never appears as waiting there (as it should), and the trucks never deliver it to the steel mill, which produces nonetheless, and I get payed for delivering iron to the transfer station.

The steel mill is automatically served by another iron mine off screen, but the same two questions remain.
