Hi 8armld8b1409
is it just this household ? Could be something is corrupted about it.
With your mods out, make sure to delete the localthumbcache file, then move the family out via the household manager (or evict them from the map) and place them in the house again to see if that fixes it.
If not, do you have any LastException/LastUIException files in Documents\Electronic Arts\The Sims 4 ?
- Delete the ones you have
- Trigger the error again
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.
Deleting the file won't fix your issue. Posting the info is meant for troubleshooting.
