Crime Scene is not being cleaned up

Probleme

Many lots still have signs of crime scenes although the case has been closed a long while ago. These lots can’t be bought furnished.

Cause

The game is supposed to clean up the scene after your Sim leaves it (as the message tells you). This does not seem to work properly.

Solution

Visit the lot with your active Sim (with loading screen). This will trigger the lot to be cleaned up
