Sims and buildings deleted from the library

Same! I've been playing The Sims for half of my life and it's one of the things that gives me joy and since this latest update (in which we were all meant to believe that it was a patch to fix a lot of the previous broken update i.e missing lots and houses) it's instead created this other adaption (that no one asked for) and has broken most, if not ALL Sims players beloved mods. I'm quite upset and angry as we all spend a lot of time and love into our creations and we expect things to work efficiently (or what's the point of paying so much for each add on?!) I understand that it's a business but I feel like they aren't listening to their audience at all.
