I opened a thread about pokemon, browsed it for a bit, did some stuff in other tabs, and clicked back to the pokemon tab maybe an hour later to browse some more.
The post had changed to one where a user was asking for relaxing game recommendations and it was loading in new comments that seemed to be from that post, but I could still see the comments that had already loaded from the pokemon post when I scrolled down.
When I refreshed it changed back to the pokemon post and only showed comments from that.
I had something similar happen yesterday.
