This is occurring for me as well, I get the unread indicator for messages in the rpol forums area. But no indicators on message threads in the games section.
I’ve tried the various suggestions in this thread but still have the same problem.
I think this is a new version of old behavior. It's happening to me as well.
I use the responsive site both on my desktop machine, and my phone, and switching between the two will cause confusion because the devices don't share cookies.
It used to be that I'd get the red number indicator on something new for a game I had last visited on the other device, then when I checked the game every thread in the game would have the New Message Comet/Fireball icon.
Now it seems the opposite happens, I'll check the game that's red, and no thread will have it despite there being new messages. Not sure which is better but it's likely rooted in the same cookie issue that I've just learned to live with at this point.
