Sims freeplay mailbox is gone?

Okay so I was doing some reorganizing my furniture in sims freeplay for iPhone and I accidentally touched my mail box. So because it was out of bounds (meaning I couldn't put it back to it's original place) I put in within the white grid. I meant to touch the check mark so it would stay there but I touched the inventory button by accident. So I checked my inventory and now it's not there. How do I get it back?

That happened to me twice… Just make a new house…
