So, after Updating FNIS Behavior through MO, 3 files get created and placed into the "Overwrite" folder, and we have to "create a new Mod" using MO with those files generated by FNIS. But I tried running the animations in the game WITHOUT creating a new mod with the overwrite files, and the animations still worked perfectly. What exactly is the purpose of "creating a new Mod" with the overwrite files? I assume it's to get the animation behaviors working properly, but then why are the animations working for me without the need to create the new mod?
