If you have the Nraas mod Mastercontroller as well as Mastercontroller Cheats, you can actually reset an object. I find this useful when, for reasons often unknown, an object becomes glitched.
From a computer - Nraas>Mastercontroller>Household>Object Reset: this provides a full list of all objects on the lot, and provides the ability to reset them. Simply scroll through the list of objects, find the 'problem child', select it and click the check mark. If it is an item which can hold items (like a fridge or a chest) then I would take those items out and place in your inventory first. 90% of the time this object reset works for me and saves having to delete and repurchase it.
