i typed in the console 'show playerfollowercount' again, and it still said zero. in fact, the dialogue options were showing as if she was already recruited, because all the 'wait here' and the 'i need you to do something' were there. The dialogue option 'Follow me, i need your help' was not there.
when i loaded, Lydia was still walking out the door, as expected, so i approached and attempted to ask her to follow me. i then saved, then installed the mod as it told me to.
i dismissed Lydia, and as she was walking out the door (of a nordic ruin, the one you get the Horn of blahblah windcaller or whatever from in the greybeard's quest) i typed in the console: 'show playerfollowercount' and it said playerfollowercount is 0.00, which means obviously that no one was following me at that time. the UFO mod told me to dismiss all followers, then save, then install the mod, then load, to get the mod working. then, I downloaded and enabled the second one.
Okay, well, i had this mod installed here: (Follower Framework) then, since i found a better one here: (UFO), i deactivated/deleted the first one with the Nexus Mod Manager.
