Finds issues in your load order and suggests steps to fix them.
This is a diagnostic tool, looking for issues in your load order. It checks your setup for basic issues with NVSE, JIP, UIO, MCM, TTW and some more.

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.
