Hello.
I'm working on a track planning mod and i have a problem with track costs. My construction has 2 modes for planning and building. When i build track directly, everything (well, almost, there is another problem with refund for parallel tracks in tunnels/on bridges) works correct:
But, if i build construction in planning mode, then go to settings and "upgrade" it to tracks(using the same mode as above), suddenly no money required:
So, my question is: Is there a way to correct this, so this upgrade will cost the same as on first screenshot? Maybe i did some obvious mistake? Thanks in advance for answers!
