I'm having this weird problem where any time I try to launch a mod, "FSO is launching" pops up in the top like normal, then disappears, and nothing happens. I tried with a few mods, but the main one I was trying to get into was the new MVPs. Changed to an older FSO build (3.8.1) and it actually launched, but then had a ton of errors. This is...frustrating.
EDIT: All I had to do was select a joystick or no joystick apparently. This is a...really weird bug.
