Whenever I boot the game, it goes to the usual loading screen, but in the side box, it says: "Checking for data modules that we either subscrib..." and no matter how long the wait, it doesn't load ANYTHING.

I've only ever gotten the game to load ONCE after I reinstalled it and all the workshop mods loaded up. The next time, it just went back to that. Is it an issue with the workshop or something? I've never had this issue with the game before...

(I played since B28)

This happens every time for me. Gotta download a new workshop item every time I wanna play the game for it to load. Really annoying. Gotta just install some useless item, then uninstall another, then uninstall the useless item when you exit the game, and install the other one that you had uninstalled. Pretty much, get two items, install one, uninstall and install other. Do that over and over.

There is a setting called DisableSteam in Base.rte\Settings.ini. Try setting it to 1 so the game don't connect to Steam.
