I upgraded to the third tier of house (large country house I think) and this time the moving box spawned inside the walls rather than outside the building like the other times I upgraded/moved house. Also when I removed items it didn't delete the square like it did before, it left the squares, and now I'm stuck with items off the screen that I can't access. Every container I had in the house was dumped into this box which is a lot stuff and I didn't think about moving them all out of the house before upgrading. All of the squares shown here were full except one row in the middle was randomly empty. I took my stuff out, tried to move the house again, but it didn't rearrange the items. I'd have lost thousands of dollars worth of items like this, including my collection of food, herbs, and fish.
(also please please make fences so I don't have to wait for animals to move when placing a house or make them invisible when moving/building. And please make moving houses separate from building because paying back the 10K just to move the house when it got placed wrong is frustrating)
