Yeah it’s working for me also. You have to launch it through the mudrunner plus. Just create a shortcut to desktop. Also sometimes I have to launch mudrunner to get the mods I downloaded because it won’t connect to steam for some reason when you launch Plus.
This version of Mudrunner Plus is indeed working with the latest update for Spintires: Mudrunner.
Although the game needs to be launched via Mudrunner Plus application. Launching the game via Steam will not load up Mudrunner Plus.
if you look at your first screenshot there, you will notice that the version number in the bottom left isn't the latest version.
(latest version is 19 11 18)
so, yes, you can use spintiresmod but it will reset your game to the version before
That is due to the "MudRunner4GbPatched.exe" which draws its current version over the main-menu and with that it attaches "D3D9.dll" with it → (18.10.18).
Although if you click on Multiplayer, the sessions you'll find will be the exact same ones if you ran "MudRunner.exe" (19.11.18).
So, is the game updated ? Yes it is, and it's only the Mudrunner Plus executable (18.10.18) which we are using.
