Just ran into a strange error: when I try to deploy a smart contract, I got the error `ContractNotInInputs`. After some debugging, I found out that this error would go away if I didn’t try to set the storage slot `0x0000000000000000000000000000000000000000000000000000000000000000`.

We’ll work around this issue by changing the storage slots we use, but this still seems like a bug in the VM.

Uh, that’s odd. How can I reproduce this error?
