I'm not sure if this is something going wrong, or just how Mastodon works.

Anywho, when I go to Communities - Subscribed and click through to this one: https://lemmy.nz/c/rugby@sh.itjust.works

There are posts that I think are there that don't show up in that view, eg: https://lemmy.nz/post/1077020

The only reason I know that post exists is because it does show up if I just go to https://lemmy.nz/ so i'm guessing it shows in the Subscribed Posts section, but if it isn't there then i'd be missing the post entirely I guess.
