It must be something weird then with editing old posts.
@dual_sport_dork@lemmy.world this is really weird but this entire post just showed up on piefed.world yesterday as a new post. I didn't recognize that it was 2 years old until I re-logged into lemmy.world today. I was curious because I didn't see any other comments on the piefed side of things. There's some weirdness going on between the two instances for sure.

Looks like there's no way to include a thumbnail when posting from piefed.world. That's a bummer.
Wow the one you're retiring has seen some things for sure! Another great example of quality not needing to cost a lot.
