Sorry, I should have mentioned I'm using Mod Organizer with Skyrim, and it's recomended to use back-date over AI. https://wiki.step-project.com/Mod_Organizer I forgot to enable "back-date BSAs" when I initially installed MO. I'm wondering whether this is something that absolutely needs to be enabled prior to installing mods, or if it can be toggled on and off whenver. Like, how does it function?
