Debug items going into your sims' inventory when moving.
ok... 1. I use debug items (such as trees, rocks, houses) in my builds. 2. I play in the lot with sims 3. I decide to move my sims to another lot and select "keep furniture" 4. Debug trees, rocks...
No, it's not a bug. The game is just doing what you told it to do. Keep Furniture pretty much includes everything that isn't part of the building structure itself.
I would suggest using Sell Furniture instead. Before the move, put everything you want to keep into the Household Inventory or personal inventories.That way, you can control exactly which items come with you and which ones get left behind.
