Gallery Help ASAP

When I go to the gallery to download new Sims from other users, it'll copy into my library just fine, but when it copies it takes away all the items or features that sim has (i.e new clothes, hair, tattoos) unless I already have them. I don't know how to fix this, help!

Sims 4 is different from 3 and 2..... custom content will not be on the Sim you download .... you must have or download the cc on the sim.... so it's best to download a sim that the Creator has a specific list of what all the cc items that the sim has

Yes, Kawaiikitty is correct. It sucks too because so many families will be loaded with cc and few people put what cc they are using, so it makes downloading sims made with cc very pointless to me. Just something as simple as not having the same skin can dramatically change the sims look. I just make my own sims with my own downloaded cc for that reason. XD
