Well, I just installed the new version, 1.5.8, all the mods libraries, a bunch of mods, many, and everything seems OK. Check your files in Steam.So, how did you manage to break the game when simply moving it from beta branch to stable branch? 1.5.8 worked relatively OK until yesterday, now the game won't even launch lol. This is amazing!
Why not just revert all the changes made in the last moment and put them in 1.5.9 and just go back to the working 1.5.8 build? Maybe you are aggravating us on purpose?
