[FNV] MO2 suddenly stopped loading my Fallout New Vegas mods
so basically, i've got a heavily modded fnv setup using MO2. at some point the game started showing these weird shredded/rainbow textures and loading screens, and then it seemed like my mods weren't loading properly anymore. the Pip-Boy was missing, the textures looked crunchy as hell.
here's what i've tried / checked so far:
- i have TWO separate Fallout New Vegas installs. one is vanilla for NVMP (as of now completely untouched, is the one actually connected to steam), and the other is my modded singleplayer install.
- i'm using MO2, located at "C:\Modding\MO2".
- i adjusted my NVTF settings to fix the crispy-looking textures. that part worked, so the rainbow/crunchy texture is no more.
- i regenerated archive invalidation.
- i deleted the renderer info file.
- i unticked mods i suspected might be causing conflicts.
- i tried removing/disabling all mods to test whether the game itself was broken.
- i made sure MO2 was pointed at my singleplayer Fallout New Vegas installation.
- i checked the executable dropdown in MO2, and the executable selection/configuration was already correct.
- launching "FalloutNV.exe" directly from the singleplayer game folder works normally. the Pip-Boy and textures are fine when i do this.
- i created a fresh diagnostic profile in MO2 with no mods enabled, and that also launched normally.
- my original MO2 profile had profile-specific INIs enabled. both the original and fresh profiles had "Fallout.ini" and "FalloutPrefs.ini", and their file sizes were identical.
- i disabled Automatic Archive Invalidation in my original profile. after doing that, the original profile launched normally with all mods disabled.
- i then re-enabled all my mods and plugins in the original profile, but the game still looked completely vanilla. the mods appear to be enabled in MO2, but they aren't showing up in-game.
- i checked the MO2 "logs" folder and opened the newest USVFS log.
- i searched the log for "FalloutNV.exe" and checked whether it mentioned "injection to same bitness process". the injection was reported as successful.
- i made a full backup copy of "C:\Modding\MO2" before continuing troubleshooting. it's around 11.6 GB, and it includes the "mods", "profiles", "downloads", and "ModOrganizer.ini" files/folders.
current situation:
- launching the game directly works normally.
- a fresh MO2 profile with no mods enabled works normally.
- my original profile with mods disabled also works normally after disabling Automatic Archive Invalidation.
- BUT my original profile with all mods and plugins enabled still launches as if it's vanilla Fallout New Vegas.
- USVFS injection seems to succeed, but that hasn't fixed the issue.
i haven't established the actual root cause yet. i'm trying to figure out why the original MO2 profile isn't applying its enabled mods, despite the game itself being fine when launched directly and MO2's USVFS injection reporting success.
i have around 200 mods in my FNV setup, so i'd really appreciate help narrowing this down without having to rebuild the entire modlist from scratch. please help me guys 🥺
