Hello, I'm Crazykilla

So I've only see this happen to me, and only on PC, but whenever I place ANYTHING in my house in Skyrim, when I come back a while later I will find it f**k knows where, it's as if a bomb has gone off and blown away anything that I place, I might find it somewhere on the floor, or somewhere where I won't see it like in a fireplace.

Is this like a PC only thing? Is there a fix for it?

It's the placement render issue within the game. The work around is throw an object down, exit the house, enter the house and then place the object how you want. It will then remain in place.
