What happens when the bug occurs? The game loads fine as normal, go to click on household I get a green flashing square where I should see my household when I click on it, I click on manage households and it doesn't show any sims, the names are still there, I click to edit household and it takes me to a new create a sim. It wont let me play any household. Before this happened when I click on sim phone it wont open for any household. Wont allow me to give toddler a bath, will pick toddler up and put back down again. Sim children wont go to school it just comes up that they are missing school and still get the phone call from the head teacher. Haven't tried teen sims. I have tried repairing game many times, saving multiple back ups, I've tried changing the graphic settings and disabling mods and it doesn't help. ☹️
What do you expect to see? When I click on sim household I expect to see my household and be able to click play. When I click on manage household I expect to see all my sims not just the names and not to go to create a new sim. When I click on the sim phone I expect to have the menu pop up. When I give toddler bat, I expect to lift toddler up and give them a bath. When the morning comes I expect to see the children go to school automatically.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. after I installed snowy escape (not straight after) also after I deleted mods using sims tray importer

Sim households not appearing, just the names, cant click play. Manage households all blank with just names showing. Clicking on edit household takes me to create a new sim.
