lelliott2011 If you have any mods or custom content installed, please move the Mods folder to the desktop and delete localthumbcache.package, then test again. You don't need to save your progress.
If that doesn't help or isn't relevant, please test in a new save.
If the new save is affected too, please delete and reinstall Horse Ranch. Make sure Steam and the EA App are closed and NOT running in the Task Manager, and kill the EABackgroundService in the Task Manager as well, under background processes. Open the game's install location, here by default for a Steam install:
C:\Program Files (x86)\Steam\steamapps\common\The Sims 4
and delete the EP14 folder inside. Open the Delta folder and delete the EP14 folder there too. Open Steam and repair the game: Sims 4 > Properties > Installed Files > Verify integrity of the game files. Then reinstall Horse Ranch and test again in a new save.
