It may be because Deceptichum is on quokka.au and that instance may not have federation issues with lemmy.world.
Oh that’s probably what’s happening, you’re right
I feel like in the past that wasn’t a thing though
You could be right in that in some edge cases federation has caught up, assuming that this was an edge case affected by the federation issue and not just something we hadn’t observed before.
I crossposted an az post to lw today and I can see some comments and votes on the lw post have not federated back to az yet. I think it’s still about 5 four days out.
Update: Federation with lemmy.world users appears to be four days behind now.
