I am sure this has been mentioned somewhere, but I was not able to find it.
As many of you may know, if a sim or pet dies inside, they get an urn. If you try to put that urn on a table or shelf it will (sometimes) float above it. To fix this, just set it on the ground out side (it turns to a tombstone), then set it back on the shelf or table (it will turn back to an urn, and will no longer float.
