I did something to fuck up my NV installation when messing with TTW, so I nuked the entire thing, reinstalled NV, and then TTW. When I try to launch it with no mods, it crashes immediately. If I launch it with NVAC enabled, it just loads a black screen with a glitchy-looking cursor. Especially weird since my initial installation worked perfectly fine. I've tried reinstalling it twice, didn't help.
Possibly relevent info:
Windows 8.1
Mod Organizer 1.3.11
Steam GOAT for both games
e: I tried disabling the .esm's one by one, and even with all of the FO3 ones disabled, it still crashes on start. Weird.
e2: To the surprise of no one, I'm an idiot. I mentioned I also reinstalled my NV installation of MO; this time when I was setting things up I checked automatic archive invalidation since I noticed it and it recommended doing that. That's what was causing the issue. Bah.
