This post on Beehaw:

@lisko@sopuli.xyz’s comment is not visible at all on the Lemmy instance while to me my comment is not visible at all on the Beehaw instance, nothing is showing in modlog though so I assume it has not been removed.

Am I unaware of a mechanic of federation occurring here? Or is something bugged?
