So I’m running the dev branch and I just reinstalled CSS because some content wasn’t working right(you seriously have to keep the game installed?), but when I went into gmod and hit “new game” I was greeted with this: https://i.gyazo.com/567c82acd6cd41d1dad43551f7fb70b6.png
So I figured that opting out of the dev branch would likely fix the issue, but when I went to opt out, the dropdown didn’t drop down when I clicked on it…
Loading saves seems to still be working, as does the changelevel console command so there IS a workaround already, but I figure this is still something that needs attention drawn to it.
Haven’t checked the rest of the main menu, but the menu itself is still there and I know there’s a similar but much older issue in the bug tracker no one seems to use (http://support.facepunchstudios.com/kb/articles/30-my-main-menu-is-missing). Unknown if it’s related though(I did recently upgrade to Windows 10).
