Don’t worry — in most cases your building, decoration, or field isn’t really gone, just hidden. Try these steps:

  1. Check Edit Mode. Tap Edit Mode and use the transparent building icon to hide tall buildings. This makes it easier to see if the missing object is behind something.
  2. Look in the store. Open the store and select the missing building. If it’s already placed in your town, the game will show it in the center of the screen.
  3. Check storage. If it’s a decoration, it may have been moved to your storage tab.

In most cases the item is simply hidden or stored, and you’ll find it by following these steps.
