The message restore appeared , it appeared to work but after restart it dropped to 60 again
Try Nostur. It has a feature that lets you know your follow list changed and asks if you want to keep or ignore the changes

Are you missing any relays since last time your follow list was full?
I don’t think so
Usually this type of thing happens when relays are missing
If you open Nostur, does it show you the notification for the follows again ?
