@picsoul Just use pre-workshop version of the game. (ver_18_01_29b) and all is good.
You can pick that one as "beta" in steam.
Now to make it easier for you.
When you have done downloaded the "beta", copy the exe somewhere (or in same folder).
Now you can "update" the game again, backup the new file. and use the backup exe to run the game. (You might and most likely will get some errors loading the new game-maps, but most should work fine).
