I see. Perhaps it's what you mentioned about Lemmy handling cross-posts of different types of posts a little differently. I seem to recall someone else mentioning that before.
If you wanted to see the post I'm referring to, here's a link to the native URL of my cross-post: https://lemmy.ca/post/68531648
If that still doesn't work, you can also search for that lemmy.ca URL above in your own instance (slrpnk.net) and the search should show you the local copy of that post on your instance.
Thanks!
