Huh, that is weird, I have missed 3 episodes as it seems - they don't show up on my instance and I wasn't notified as a subscriber. Did a very quick check of logs in the PT admin interface, but nothing stands out on my side as a federation issue. (But I may have missed something for sure.) @ozoned@piefed.social - do you know what could be the issue? Will try to see if I find more later today, too.
I guess as a workaround I can try watching on mastodon/piefed - although I am not really using the former at the moment, and the latter is not the best for following PT yet.
