October last year was the last proper patch release, the other three were minor hotfixes.... I play in offline mode generally and went online a month or two ago, game updated through steam ...
Nothing that should suddenly prevent all content of a mod to load at all or as you said "NONE of it is registering ".
what do you mean by a folder tier too many?
I had to assume you downloaded a packed mod in rar, zip, 7zip formats and unpacked it.
Unpacking can create an additional folder which contains the mod, depending on program, settings, method.
Using that will prevent reading of the mod files, unless the mod folder inside is moved out of it.
PS : Troubleshooting of mods is better suited in the modding quick questions thread.
PS_2 : First you speak of "will still load but its like none of the content is being read. ", now you said "then the mod started crashing on start ".
What now ?
