This is a diagnostic tool, looking for issues in your load order. Right after game restart, it checks your DLL plugins and mods for inconsistencies, shows the report on the screen and saves it to fnvdiag.log in the game’s installation directory. After that, the plugin can be disabled, as it performs tests on every game restart.

 

Currently, it checks for basic issues with NVSE, JIP, UIO, MCM, TTW and some more. Down the road, it will be expanded with tests for mod incompatibilities, missing files, harmful and outdated mods, mod alternatives and so on. Please, suggest tests to perform in comments.

  1. You may need to update the detection of FNV Mod Limit fix, it was recently updated to 3.0 in may of 2022, and it now uses a new console command to test if it is working correctly ( “IsDLLLoaded mlf” instead of “IsDLLLoaded mod_limit_fix”).
    when I checked the Diagnostic it said mod limit fix was undetected, but checking manually though the console command said it was working fine.

  2. Absolutely brilliant for fixing issues both small and large

    This should be a requirement for any modded game. Thank you!
