Interesting fact - CC/mods X moolas kits

I intentionally bought a few moolas to test if they would work with the new update, as our previous CC doesn't as the mods. And surprisingly, not so surprising, they work perfectly fine. If we all think, they are kind of a CC content, so here's my question, why??????? Why things that we already have, that we did not buy from them doesn't work and the package that I spent money on it does??????  And what is pissing me much more is that houses, sims and buildings that I spent hours building are gone, they doesn't even show in my gallery any more, this is so ridiculous and aggravating that makes me wonder a bunch of things. I really hope they fix this very soon and that all our work on the game isn't lost, because this is really disrespectful with us. I have all packs, expansions and kits from the game, every single one of them and now all of I've done seems to be lost. Very very much unhappy right now
