As I mentioned in a previous reply to this post, some posts and replies did not show up after piefed.zip was brought back up after the security fixes.
My post has since showed up, but none of its replies.
The other post I mentioned also still has 0 replies on piefed.zip but 26 on lemmy.zip.
I now noticed a few more posts on !anime@ani.social created last week (around the time of the maintenance?) showing up just last night too, probably because they were updated by rikka (the resident bot of that community) and the changes propagated.
However, they showed up with 0 replies on piefed.zip whereas there are replies on lemmy.zip:
Thread 1: piefed.zip lemmy.zip
Thread 2: piefed.zip lemmy.zip
Thread 3: piefed.zip lemmy.zip
Not sure if this is hard to fix or not, just want to bring this matter to your attention so at least it is known.
