Thanks, all. Good stuff.
I decided to address it via brute force. I uninstalled and reinstalled Vortex, and I'm starting with one of my Fallout 4 deployments to fix first.
The mods are recognized, without their meta data, meaning they were all listed by name, with an ID number, but without the Version column populated, nor author, category, etc. That all makes sense. Example:
So I ended up reinstalling each mod, from Nexus, allowing them to over-write the existing version. I could have simply dragged them, from the downloads folder, into the 'Drop Files' area, but I really wanted a) the 'Downloaded Time' value to equate to a true download time, and b) ensure I am getting the proper version installed. The latter is due to previously having multiple versions of the same mod due to multiple versions of FO4 on the PC. I'm to the point where I just want to finish my SIM Settlements 2 run-through and not bother with London until that is done, and thus I don't need different flavors of the same mod simultaneously. In addition, redownloading the game allows me to have the 'Open on Nexus Mods' option again, and thus also allow for automatic checking for mod updates for each mod.
I keep launching the game and letting my save tell me what mods are still needed, and I back out and add them in.
The act of reinstalling each mod is somewhere between a PITA and cathartic, depending on my current mood.
@vortexposer, I laughed when you mentioned creating draft collections, because this idea occurred to me, about a month ago, and I thought, 'Christmas is coming up. I'll do that in January.'. {sigh} Coulda shoulda woulda! Once I'm all reinstalled I am going to do that. Thanks for the reminder!
