My sims & City Living disappeared together

hi there! like the title says, both my City Living and my actual sims' household have disappeared. this happened within the last week. when i open the game, it tells me some data isn't available and starts me out in the world mode. when i go to my actual world/my house, it shows my house is vacant. my sims don't even show in the bottom left corner. i've been doing some research and i noticed others say the City Living DLC has been taken off Playstation+ and needs to be purchased to keep playing it. if i purchase it, will it bring back my sims/household too? has anyone else had this issue? i have already tried to uninstall and reinstall, but still no luck. please help lol.
