Bizarre Inventory Problems / Related to Cannot Build

(Continued from/related to, I believe, crash on save issues I was having previously. http://answers.ea.com/t5/The-Sims-3/Constant-crashing-when-saving-after-building/m-p/551210 )

* It seemed my issues with being unable to save had been resolved. I moved into a prebuilt house, I was able to build on that house as well as buy objects and place them. A critical test passed in the replacement of ruined umbrellas from inventory. Game saves were quick, loads were quick. Game play quick.

* Insert some couple hours of play here. As I grew a bit more confident (and struggling with holidays and 3 day work weeks trying to get to lifetime wish fulfillment) I had a lot of time on my hands. Remodeling done, no problem. Noticed one achievement (tossing elixirs) had been lost when previously earned. No proof on thesims3.com player page; suspect a crash too close to winning it was the culprit. Re-earned it. And... finally decided to start moving objects out of player inventory into fridge or bookcase.

The ONLY suspicious behavior up to this point was attempting to do a private reading on a sim in town to complete an opportunity and as the reading SEEMED to finish, the sim reset. (Not one I was playing.) Just disappeared and went home it seemed. I tried to track them down, and got the 'no no no' response repeatedly, even though best friends. All I could surmise was that they already had their 'private reading for the day.' Later completed opportunity without issue (day or so later).

* And so, problems begin when I begin putting books into bookcases. I start sorting books into various bookcases. Skills into one, recipes another, self-written another, childrens, fiction etc, fishing, so forth. The household sim who carried the books from the original house I couldn't build walls or delete them in ... I had been manually doing this and I thought hey, fancy 'put away books in inventory' button. So I clicked it.

Something odd happened. A ton of books appeared out of NOWHERE that I could not account for. Now, some items seemed to be missing after the move for this one sim (just the skill awards for maxing a skill). But these books came out of nowhere -- not the sims inventory and they were not in household inventory as far as I could see previously. No bookcases. I was CAREFUL on the move. I pulled books out of the bookcase into personal inventory, and deleted the bookcases. Same with fridge etc. I wanted to maintain quality of honey, fruit etc. I wanted control over the inventory. I just let a few miscellaneous things go into household, and I *manually* put them there. (Gnomes, wildflowers, rocks, etc.)

So these books appeared out of nowhere. I sorted them into bookcases. Things started to seem to slow down. I got to the festival site, and wherever I clicked on the ground, instead of 'move to' and other typical interactions, I got 'use' interactions for things that should have been deleted. Trash. Read a book. Other things. On the grass. Invisible objects that are not there. I try to read one. No path to object.

This seems bad. (Duh.) I save, thinking maybe quitting and restarting will clean up trash.

* Restart the game after too long a save and waaaay too long a start up. But no crashing. Things seem to be working for a little while, ten fifteen minutes. Then I send a sim off to the toilet. Misclick and hit the floor and get 'read ... book title.' No matter where I click on the floor I get this. Pretty sure if I try to put it away, I'll get no path to object.

Now, what did I do? All I did was sort through the books, and delete a lot of extras/duplicates. I don't need 12 copies of cooking 1, or 16 logic 1, or 3 of this child's book etc. I dragged them over the 'Drag here to sell' and sold them. Only the same freaking thing that SEEMED to happen the other day in the old house happened here. The objects sold, and duplicated themselves and dropped invisible copies all over the place.

The other day this most notably happened with umbrellas. Most notably because they break all the time, and if I have to replace them every other day, by going into build/buy (why they don't just have a click/replace option I don't know...) buy one, put it on the floor, drag the old one into the trash from the inventory of the player, and then put the new one into the inventory. Only more than half the time, the OLD broken one ends up sold and also on the floor.

I found I had to level my kitchen because I couldn't get to the fridge. No route. I had to move it and I could use it. No rotten food blocking use, none of the 'typical things' wrong. But -- after leveling the kitchen, repeatedly dragging and dropping every which way and replacing stencil, one time dragging harvested vegetables to the fridge I saw some on the floor. No, I did not miss. One time moving food to the fridge and selling money tree harvest, I sold the money and it ALSO ended up on the floor.

Is 'drag here to sell' an open hole through to the empty space of the game? It just floats around everywhich way?

This is essentially repeatable. I can keep dragging stuff to the 'sell' space in inventory, and eventually I'll end up with crud on the floor. No, I'm not missing. I can make double the money. I don't want/need the extra 54 simoleans from a broken umbrella. I don't want 200 invisible books that now make the floor unusable.

So. Known issue? What do I do? How do I salvage the game? Do the move out of lot, save to bin, nuke lot thing?

Will quitting the game get rid of invisible trash floating around community lots, does it force a clean up?

I am NOT using any mods. Just my store cc, all my expacs/stuff packs. This is NOT a bug I have ever had before in four years of playing.
