Ok so recently my friends and I have put a ton of time into building a city, but it was on a secondary google account that I had only used for the Aternos server. In a fit of cleanliness, I deleted the account without thinking of what would happen to the server. Sadly, I am now unable to get access to the world that we worked hard on (and no I didn't download a backup, my lack of security is very apparent to me right now).
I don't know if there's some way to access the world file (which is literally all I need from the server) since the Aternos account is likely still out there. Hopefully there's some way to find the missing world.
