The new Horse Ranch expansion world is not appearing

@secretrev09   Hi!  Many times this issue is related to a mod, which seems to have been the case for @Ioney6 based on what they said.  If you have any mods installed, please move your mods folder to the desktop and delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing.  You may also want to run a game repair.  Please come back and update if you're having this problem without any mods installed.
