The issue

An entry with LogIndex: 1009, ID: 670, Type: Settle cannot be reloaded to localUpdateLog because its parent Add entry(htlcCounter=670) cannot be found in remoteUpdateLog.

This entry is loaded from db using bucket remoteUnsignedLocalUpdates, and it's used to settle an incoming HTLC sent by the remote. By looking at the remote's closing tx, our local commit, and the entries in remoteUnsignedLocalUpdates and unsignedAckedUpdates, this Settle entry was actually received by the remote, and we did remove it from our local commit, but failed to remove it in remoteUnsignedLocalUpdates.

Remote's force close tx.
