I know many players abuse the option to overlap objects (or maybe it's a bug?) to create those +18 rooms, and the developers probably don't like that very much. I also like to use this option to overlap some furniture, like placing chairs closer to tables and other things. But lately, the furniture I use for this is disappearing from the decor (it's still in my account), and that bothers me. This option really helps to make the scenery much prettier and more to our liking. For now, my flowers around the tree are still there, but I think it won't be long before they disappear too 🙁. Isn't it beautiful?! So, I'd really like to know if doing this is wrong?
P.S.: Some furniture is also disappearing from my account, as I've seen people reporting here about the museum walls and the toilet paper holders.
