And to clarify .. I still have my contacts - I just lost my damus relays (kind3 content was not copied into the replacing event).
And I didn’t event follow anyone by memory. I think they inject the current relay into existing data. Not 100% sure, as only half looked into it.
I may have lost a few contacts, but 95% are still there. I haven’t diffed anything yet. I have backup, so will likely just restore.
