OOC: Virtual Town Crier
The thread is odd for me too on both desktop and mobile.
If I had to guess, it looks like I'm seeing private messages about the interesting things that people received. However, those messages fall outside the "borders" of the usual RPoL frame. So it's like I'm seeing the posts with no foreground, only background. It's very strange and I've never seen anything like it in ~6 years here.
DM, will you check to see if you inserted any private lines and, if so, were they to an individual, multiple recipients, or to a group?
