Some communities seem to have stopped federating with Mastodon

No idea what's going on or whether the issue is on Piefed or Mastodon's side but hear me out.

See attached image. Posts from !mrbungle@piefed.social aren't federating with Mastodon anymore. I'm following both the community and my Piefed account from my Mastodon account on mas.to. The last post visible from Mastodon was created on Feb 12th. The community isn't very active but there have been a few new posts today and in the past few days. Same issue with !enniomorricone@piefed.social.

This doesn't happen with all communities, though. For example !movies@piefed.social is federating just fine and I can see the latest posts, including those created today.

Curious to hear if anyone else noticed that! Any ideas what's going on? :)

I am the author of all the missing posts by the way. Could it be something wrong with my account?
