I have lost quite a lot of my inventory, including textures, scuplties and countless other items that were expensive. How can I get them back. I have already done the clearing cache with no luck.

I get this "mattress request" when I am in one part of my house. If I leave the room it goes away but never goes away from the room. It is annoying and I want to find out how to get rid of it.
