So, why is that whenever I come home (Whiterun...Breeze..) I find my carefully placed items lying on the floor as if I just dropped them from my inventory? WTH!?

I believe it has something to do with loading the room so there's really nothing you can do about it.

I noticed this too - I always loved house decorating, it was a big part of the charme of the ES games for me. Was fine with Morrwind, got worse with Oblivion and is nearly impossible with Skyrim now. But this is really the only big Minus I have experienced with the game so far

Yeah. In Morrowind, it took a few tries to get an item where you wanted it, but it STAYED. Oblivion: items were a bit tough to place, but they were explosive. In Skyrim, placing is about the same as Oblivion, but the stuff always loads on the floor...

Cy Tolliver: Not always Have hope - I have a bowl staying at the same place on a dresser for two days now ^^

I'm going to comment on this one...

I've spent several hours in my Breezehome filling book shelves, putting shields and swords up on the walls and rack... But every time I come back home
my stupid goblets are on the floor, the mead fell off the shelf, and the two necklaces placed on seperate dressers are on the floor as well. GRRR!

Something similar happened but upstairs is a bedroom well there was no bed but a random door but when I left the house and then came back it was all fixed, confused.

One time I loaded up my game from inside my house and none of the furniture loaded up but all the little decoration items and food did so it all just fell into the floor. I had to leave the house and comeback in to get the furniture to load back up, but of course everything stayed on the floor. I now have a few dozen cups, plates, and pieces of bread laying under my dining table.

This sounds like particularly wonky physics behavior, but every Bethesda game has had these sorts of problems since they started using the Gamebryo engine (Creation still has Gamebryo as its core). Dishes and forks "floating up" out of tables and rearranging themselves because you picked up a nearby piece of cheese, potions blasting across the room when you just barely nudge them, your companions crashing through scenery items (set tables in an inn, for example) sending things flying, and stuff on shelves knocking against other stuff on the same shelves, creating an ugly jumble out of something the level designer (or you, if you're decorating your house) spent time arranging.

I liked Morrowind's item physics much better: It didn't have any. You put a plate on a table, the plate stayed there. You put some gemstones and ingredients on the plate, they stayed on the plate.

This kind of stuff is going to keep happening until they move away from the Gamebryo engine entirely.
