I created and registered an account after completing a wallet export on my gui client. When I updated I didn't do a new export, I just wiped my data directory and imported my wallet json. That account no longer shows up in my accounts. The transaction that registered the account is still visible but shows as being sent to UNKNOWN. I had assumed that the export exported a master key that would pull all registered accounts upon rescan. It looks like I was wrong. Is that account lost forever, or is there some way of retrieving it. There are no funds in it, I just liked the name.
