Wow that's crazy. There is no single function that changes all of them at once to have a bug on. Can you check your realy lists were erased or if it is just locally?

Just locally.
It happened again. An app restart restored them.
I'll raise an Issue.
Does it say 0 relays on the left drawer or just empty list on the relay settings?
It says 3/3 in the draw. Nothing in the actual list.
Normal is 5/5 for me.
