Why can't I start on the maps which do not allow me to select any trucks?

I downloaded two maps that don't allow for the selection of any trucks into the game. I can't even start the maps as it doesn't have the start map button as an option to click on. Please help. Thanks.

Try with the beta game version 18_01_29b. With game version 18/03/06 you can't play manually installed maps. ONLY workshop maps.

Manually installed maps work for me for some reason, even-though I have the new update installed.

Manually installed maps will work with the updated version of Spintires: MudRunner, they just need to be converted to the new version using the mod conversion tool.

did you get the maps in question working, Cody?

You don't have to convert the manually installed maps if you have SpintiresMod.
