New Posts in Thread Icons that work

Two examples right next to each other. It seems that new posts in thread icon appears after some time rather than after a new post. There are clearly no new posts in either thread.

Did you press the "back" key on your browser? That will cause the icons to remain unchanged.

This is intentional behaviour. Basically, there are multiple ways that "read" icons can be implemented, but to make it precise uses a lot of resources, which is infeasible for a (relatively) large forum such as Smogon. The implementation that works for large forums, and hence the one you find on Smogon, marks all threads read when your session ends; i.e. you are inactive for a half hour. Your own new threads will also be considered unread until your session ends.
