I had this as well. I don't know about some of the details you went into. I just know that food and fruits and vegetables got put into household inventory during the move process. When I try to drag it out and place it on the new lot, it vanishes as soon as I let go of it. Same thing happened with the fruits and vegetables. They just disappear when placed. If I try to drag a fruit to a planter it will sometimes stay and can be planted and sometimes it vanishes.
Another thing that happens is that any books that were placed in household inventory during the move vanish when I try to drag them out and place them on the lot. If you had a bunch of books that got placed in household inventory during the move and you want to keep them you better just make a list of what they had, sell them and buy them again from the bookshelf. Books a Sim has written should probably be placed in a Sim's personal inventory BEFORE the move cause they'll be unrecoverable if they end up in household inventory.
My game is un-modded and I have every pack up through City Living.
