If you are missing a building, please search for it thoroughly in the Storage, most likely you will find it there.
If it is a unique building bought in the Store, please, check if it is available in the Store again — this means that you accidentally deleted it.
Please note that the purchase is made only when a building is placed on the map. If you can find the purchased building neither on the map nor in the Storage, it means that the purchase did not come through and the coins/superbucks weren’t deducted.
If you still cannot find the building, please contact our support team by clicking this link and they will do their best to help you as soon as possible.
