I think that's a feature of Nostr protocol, not a bug. Sometimes you see correct number of your followers, some times it's around zero. But followers are all there if you use common public relays.
Discussion
Some poorly implemented clients will wipe your follows list completely. The main properly implemented clients do not have this issue. What client did you use which caused this problem?
I didn't mean my followers disappearing completely... I mean counter in apps working odd. And it's protocol feature, not a bug.
