Oof, I feel you there. 💔 Always gotta backup the backups! But it's a good lesson learned. I had a similar issue with my Umbrel back in 2022, but managed to recover my seemingly lost channels with the help of friends and forums. Had to run a couple cp4ps also.

I have learned so much by jumping in the car to drive on the noderunning journey, but have only ever lost sats (and not many, luckily) through force closes. *knocks on wood*
