[BUG?] Bulk convoys not recording revenue

[Matthew]

I have a number of bulk lines on the Bridgewater-Brunel map that are not recording any revenue, even though goods are being transported. I don't know why this is happening nor did other Discord users, it seems.

Here are some examples:

Brockleigh Bulk Line (truck)


West Sea Brockleigh Coal Ship


East Sea Swinpike Coal Ship

(Note that in this third case, a tiny amount of revenue [0.01¢] was recorded).

A save game from the server is here and these are all Great Central Railway | Cambrian Railway lines.

All the lines affected share the same characteristics: they are relatively short lines at the end of a journey that involved a much longer line. This diagram (not to scale) shows the most relevant portions of the network:



But this might be coincidental.

I am aware that it is difficult to debug server saves, but I thought that I would start this way because it's very possible that this isn't a bug, just some part of the Extended rules that I've forgotten about.

I believe that this is related to the fare stages feature: certain goods types, including bulk goods, produce a diminishing per kilometre revenue the longer the journey until, eventually, they produce no additional per kilometre revenue.
