Read through that before making the post, but admittedly making use of a Mac is hamstringing me here on some of these accesses to those things.
As a small update though, I started going through the model manually to try and identify pieces, and at least 12 of the removed pieces were the "2-color short legs" (the ones where you could color the upper/lower parts and the 'ankles' separately), so that piece probably got some kind of update. I've replaced all of those now.
