Hello,
it seems maintenance is doubled for this kind of object.
Could you be more specific. This was not touched for ages and in a short test the right numbers were shown.
Certainly! Attached is the "offending" example (I compile it with makeobj 49). You can see the maintenance is 100, but in game (tooltip for the icon) it appears to be 2c.
I mean the trolleybus wires, called TrolleyBus_Electrification.
Well, the maintenance is specified for the old defualt length of a month. When using other number, the value is changed accordingly.
Then it's solved! Thanks!
