Highways seems to doesn't work to the game as a new building.

I tried all the essential changes on the following files: export_descr_buildings_enums.txt, export_descr_buildings.txt, and export_buildings.txt.

And also, all the highways & c_highways TGA files are in their UI folder locations and subfolders (eastern_european, middle_eastern, northern_european, southern_european).

The game loads but before gets to the menu, craches.

In system.log.txt file (where all the game errors posted) says the following:

[script.err] [error] Script Error in data/export_descr_buildings.txt, at line 2972, column 17
Invalid upgrade specified

(It means that the game does not recognizes the new building upgrades in the road sections of the file).

Is something wrong? Here is my copy from export_descr_buildings.txt:

    }
    plugins 
    {
    }
}

The same and with the Castle roads entries, (c_highways)

All works fine except the export_descr_buildings.txt. missing something?


Please, can anyone to post his copy of road sections of this file?
