@ThatCraigGirl You're been seeing common reasons that people get this message. Not all common reasons will apply to all cases. If you don't use any custom content and you don't have any downloaded Sims or downloaded builds -- you play completely vanilla with no mods or CC and only Sims and builds you made yourself in your save -- then the common cause would be an EA App problem with not all packs you own loading properly. Support for that is available at https://answers.ea.com/t5/Bug-Reports-Technical-Issues/Missing-Games-DLCs-in-EA-app-Library-Feb-2024/m-p/13454449
