Building and removing crossing results in different maintenance

[ceeac]

Steps to reproduce:

• Start a new map and verify that monthly maintenance is 0
• Build a 3-tile road on flat ground
• Make a crossing by building rail track across the road
• Remove both road and track using the way removal tool
• Notice that monthly maintenance is now not equal to 0

I am having some trouble reproducing this, I am afraid. Can you confirm the precise order in which you add and remove the road and railway?

For me, the order does not matter, and I can also reproduce the bug with both the way removal tool and the generic remover tool. Maybe the monthly maintenance of a single road tile is too low depending on bits_per_month and/or meters_per_tile? For me, a single tile of MacAdam road has a monthly maintenance of about 4 credit-cents (base_meters_per_tile = 1000 and base_bits_per_month = 18 in simuconf.tab). This is also the amount of monthly maintenance that is left after removing both rail and road which leads me to believe that when a single way of a crossing is removed the maintenance costs for both ways are reimbursed (which should not happen).

Can I trouble you to upload a saved game where you can reproduce this issue on the basis of a precisely described sequence of events?

• Load the attached save on the master branch
• Open the finance window and switch to the "Months" tab
• Build 3 tiles of "Steel track (85 lb/yard)"
• Build 3 tiles of "MacAdam road"
• Activate the object removal tool by pressing the r key
• Remove all ways
• Notice maintenance is now +4 credit cents

[jamespetts]

Thank you for that: that is most helpful. I believe that I have now fixed this. I should be grateful if you could re-test to confirm.

I can confirm that the bug is no longer present in the master branch or in the ex-15 branch.
