Yup, ran list unspent and its not there... Is it possible that the address somehow got removed from the wallet?

Is there a reason why a transaction's unspent output would go to an address which the wallet says it doesn't own? The transaction consists of 2 inputs (which are owned by the wallet) 1 spent output, also owned by the wallet, and 1 unspent output seemingly not owned. Cant find the private keys anywhere for that unspent address
