Noble heavily utilizes the in-place-testnet command to test upgrades and functionality against state from our live networks. On our devnet, we are testing functionality that requires vote extensions to be enabled. When running the in-place-testnet command, we always get the following error:
panic: failed to reconstruct vote set from extended commit: vote.ValidatorAddress (4AA2B5473063FA3FAB799844EC3519744806FCE5) does not match address (XXX) for vote.ValidatorIndex (0)
 
Our hunch is that there is missing logic in the testnetify function to properly clean existing vote extensions from the validator set of the live network.
