Each instance stores a copy of the messages and posts on the other instances. Federation means the posts and messages sync across the different servers every so often. Ideally this would happen instantaneously, however sometimes servers can get overloaded and take a while to sync comments.

I see you’re on lemmy.world. This instance is usually quite fast, but it has been a little slow over the last 1-2 hours (not sure why, could be any number of reasons). That means the syncing of messages may be delayed. Give it some time and the messages will come through!

Another potential reason is, kbin and lemmy use the same software but are slightly different. kbin-lemmy federation was only possible 2-3 days ago (before that you can only sync across lemmy instances) so it may be a little buggy.

Well from my own experience so far, lemmy.world is one of the better ones

I have a goji account on 5 different servers, just until I figure out what works best for me. Looking at a post with 48 comments on its home instance, from the other instances I see comment counts ranging from 0 to 39. So there are clearly a lot of wrinkles yet to iron out.

So it seems it’s not a kbin issue, but a federation issue in general right now.

I feel like the devs are focusing on more pressing issues at the moment, like security, stability, scaling, accessibility and mobile apps… I’m sure they’ll figure out what’s going wrong with syncing, but it may be a minute.

Didnt Lemmy.ml and beehaw defederate a lot of or all lemmy instances?
