Byt ner till 1.10 så löser det sig enligt promods.
"For those that are on Steam, it is likely that your game version has updated to version 1.11 by now. As usual, the 1.11 update contains some huge changes in the map format and any map that was running on 1.9/1.10 will not work on 1.11. Unfortunately we have some really big problems in making our map work on 1.11 and we have no idea when we are able to release an update of ProMods. To give you an idea; the current version makes AI cars and trucks fly through the air and the game regularly freezes or crashes to desktop. We're working together with FLD and SCS to make ProMods stable again but at this moment either you downgrade to 1.10 or you will have to miss ProMods for a while.
To revert your Steam game to to 1.10, right click the game, go into Properties, select the BETA tab.
