I had a weird experience 3 hours ago. When I run NMM, it prompted me some updates from the mods I installed, so I agreed to some of them. It installed for about 20 minutes and some requiring my approval to overwrite and some simply installed themselves without prompting me. The installation occurred during the Nexus Mod Manager is loading. When NMM finally finishes its installations, to my surprise there are new mods installed into my Data folders, some were doubly installed (one were installed 21 times Tytan's Multiple Follower and Trainer, I never approved of this). When I loaded the game, it told me some files or data are no longer installed, some of my installed mods were removed or altered, some mods I did not approve of were installed. For nearly 2 hours I tried my very best to reinstall or restore all my mods, but I've given up and had to uninstall all my mods for it was having confusions, missing files/meshes/textures/scripts, some body mods, presets, hairs, eyes, eyebrows, environment mods were altered and or removed or replaced. I hope there's an explanation as to how this happened. Thanks.
