First I created a wallet, and sent ether to it. Then I created a contract and sent some ether to it, and had a balance in both wallet and contract. Everything looked good. Then I closed the Expanse wallet and reopened it, and the contract was gone. My main wallet is there, but not the contract. I have the address for the contract but do not know how to get it back.
How do I fix this and prevent this from happening again?
