Sorry if this reply is in English, but I was able to fix my game with KarlCharlson's missing mod by following the steam community guide here. https://steamcommunity.com/sha…iledetails/?id=1990998992
If you have a recent backup of the mod, all you have to do is copy the mod folder into your [C:\Program Files (x86)\Steam\steamapps\common\Transport Fever 2\mods] folder, load the game, disable the workshop version "TPF2-Addon-Script_-_verbesserte Straßen 1.811" in the load save game menu, then load your own version instead.
If you have an older backup of the mod, or do not have a local backup at all, you can download it from here. Edit by Yoshi: Removed link due to copyright reasons.
However, if you have an older backup or download from above, you will need to replace/copy several .lua files under [\res\config\streets\standard] in your replacement folder version. You can do this by copying an existing .lua file and renaming it to the missing file resource error message you get when loading the game with the replacement mod. For example, I had to copy and rename:
-town_hexa_personway_3.lua
-town_asphalt_personway_3.lua
After renaming, you should be able to load the game and remove any mods permanently and continue playing.
Good luck.
