After a recent rescan, the node still shows UTXO's  in the `lncli listunspent` output. Most likely due to using a pruned node (since the transactions are over 2 years old). To try and resolve this the Bitcoin node has been changed back into a proper full node.

Another wallet rescan will be started soon, to hopefully resolve this invalid UTXO state once and for all. During that time the node will be temporarily down because of this. Apologies for any inconvenience caused.
