When we detect that the remote commit has been published, we spend our anchor output from that commit if the fees are too low and we have funds at risk. But if the remote commit is then evicted from our mempool, we cannot publish our anchor tx and must instead skip it, since we don't provide the fully signed remote commitment to the publisher.
We otherwise error when calling
fundrawtransaction
, wherebitcoind
fails because it cannot find the external non-wallet utxo. This change gets rid of those errors that can be quite confusing for node operators.
