Just guessing, you might be the first person to try to visit that community/magazine from your instance, so lemmy doesn't have the posts from before trying to federate.

There should probably be a message after federating a new community that tells people that old posts aren't retroactively added to your local instance (unless done manually or unless that changes in the future). Or just something that tells users when a community was federated locally.

Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !leagueoflinux@kbin.social, !leagueoflinux@kbin.social
