In response to post #37063440. #37063825, #37064090, #37064100, #37064755, #37064890, #37065120, #37065405 are all replies on the same post. So, I tested something. I removed plugins.txt from appdata and the root folder. I also removed loadorder.txt and dlclist.txt. I opened NMM, which only showed the official esms under plugins. I loaded a previous loadorder from a .txt, then launched via NMM. When I tried to load a save, it gave me the missing plugins message. So I went into the mod library menu via the 'mods' option on main menu. Activated all the plugins. Reloaded data. Then quit the game. After all this, I now have a plugins.txt file in the root folder which I believe NMM created, as it shows my list of mods with * behind. Then there's a new plugins.txt file in the appdata, which is blank. And a new dlclist.txt, which has an alphabetical list of all the plugins I activated via the 'mods' menu within the game. I don't know what all this means. lol
