Not only did it delete my relays, it apparently also renamed my account, changed my bio, and removed my avatar & nip-05.
Just setup an nsite:

Just placeholder content for now, will update soonish. A very cool NIP and the process isn't too hard, just be careful to reject the relay list event or it'll delete all your relays and replace them with the nsite ones you selected.

Re-ran it again and was able to upload the new version of the site without issues. Just need to make sure to only approve the blossom media uploads and initiate nevent, rejecting the rest of the requests in amber (or you nsec bunker of choice).
Update: this was absolutely my fault, there's a setting to not overwrite profile data.
