Plugins + Mediacore disappear after most recent Premiere CC 2014 update?

Question

Just updated to the most recent version of Premiere and when I loaded a project, I found that all of my plugins had disappeared. Thinking it was just a Mediacore issue, I went to Library/Application Support/Adobe/Common/Plug-Ins and found that my 8.0 folder was missing! And more than that, almost all of my plugins (Red Giant, Twixtor, FilmConvert) were missing from the 7.0 folder!
Any idea of what's going on and what I can do to fix it?
**EDIT/UPDATE:
Anticipating that I might be instructed to re-do my search for the mediacore by starting at Macintosh HD (Instead of user library), I found an interesting (but unhelpful) difference from when I started at my user Library - I also found my plugins folders for CS5 Through CS6, which contained all of my plugins.
The 7.0 folder was still empty, and the 8.0 folder was still missing. See screenshots:

Answer 1

Sort of found a fix:
- Simply moved everything from my CS6 Mediacore into the 7.0 Mediacore, and that put all of my plugins back into CC 2014.2
- Had to reinstall FilmConvert, which isn't too bad, but it's annoying that I have to update all of my RedGiant plugins again. May as well reinstall everything.
It's weird how the 7.0 folder now communicates with CC 2014.2, and its super inconvenient that it basically got rid of all my plugins post-CS6. Luckily just reinstalling to the 7.0 seems to work.
