I'm having the same problem, was a solution ever found? so far I have f4se installed correctly- followed gopher and gamerpoet to be sure (shows up in game command line check) MCM- shows up in game looksmenu- gave me some new options so I assume it's working correctly CBBE- installed without issue but I haven't gotten to a point to test it as I'm brand new to fallout Bodyslide-working AAF- installed fine, followed a guide, grabbed the check file AAF_GFV.exe off the discord When I ran it the scripts were not found but they were installed through MO2 I had to copy a set to the game data directory for the tool to see the scripts and then everything checked green.. except AAF isn't installed. According to the tool so it's either a huge bug or MO2 is causing issues. EDIT: I figured it out. If F4SE is being verified in game but AAF isn't initializing this should be the fix. You have and edit a "Fallout4Custom.ini" file usually located in "Documents\My Games\Fallout4" open it and add under any text you see: Archive]bInvalidateOlderFiles=1sResourceDataDirsFinal= Save and now you're ready to mod and everything should work according to the AAF guide, thanks to Caliente's CBBE install instructions I figured this out. All the tutorials and guides LACK this simple step but with Skyrim modding editing .ini is the very first thing you do so I was shocked that F04 didn't have any type of .ini edits and searched around. Nuked everything and reinstalled, I caught it as I followed the install instructions of each individual mod the second time around instead of following the guide which I used as a guidlne. Anyway I noticed the Skyrim modders who ported over mods were the only ones to put this in and generally have way better install instructions and option explanations while F04 modders talk about their mods, post pics or vids and leave itty bitty install instructions at or near the bottom. Beginners will find this very frustrating, I hadn't done any skyrim modding for a year or so then picked up f04 so I was rusty. I think as a whole Skyrim modders generally seem better. Anyway hope it helps
