So although there are active threads in this forum, they're not showing up on the home page? It's only for this specific forum, the others seem to be working fine.

This forum showing no recent posts:

going into that forum but showing the recent posts:

And now all of a sudden it decided to start showing??

The calculations for subforum posts are occasionally a little weird and other things can override it very easily. It's something I'll be figuring out in Salerno.
