I've had this happen with a few times while looking for communities. Does kbin not fully federate with Lemmy yet, or is there a delay in the federation syncing up?

The most recent time this happened was with the retrocomputers@lemmy.world community. Search magazines for "retro computers" did not show it. Going directly to kbin.social/m/retrocomputers@lemmy.world URL returned a 404. I then searched for retrocomputers@lemmy.world and the community appears in kbin at the same URL, and I can subscribe but no posts/threads are visible.

What's happening here - does someone have to manually search for a Lemmy community address before it will start appearing in kbin?

I think the same happened a few days ago with gameboy@lemmy.world but now that does seem to work normally.

I've also seen a few kbin magazines not appear in Lemmy either.
