I'm looking for a mod (if such one exists) that will keep my loose items (bowls, fruit, etc) from flying to the floor.
I know that there was a custom house that had this function disabled so I know it's possible.
Can anyone please help?

Do they fly to the floor possibly because you're running without Vsync?

I had vsync turned off via the skyrimpref.ini file (I think that's where it was) under "Display" but I deleted that and saved so that shouldn't be an issue. If my sword or anything hits a table that has the bowl stuff goes on the floor
