In Step 4 after creating the smart contract we do not get a message saying "Sender address does not have any unspent outputs." Instead the contract is deployed but under a completely different sender address and thus hash address. From here I'm not able to ever delete this contract even when using the sender address in the kill operation.
I'm banging my head on this trying to understand it. We need you cryptominder, you're our only hope. ;)
