If you can see this - some threads are not showing up.

They show when looking at the different Forums and that thread was the last one commented on but they don't show inside that Forum.

There was a tread about No Puppies from DesertRoseKennel that was commented upon by ZodiakGSP. It shows in the Forum list as the last thread commented on in the General Discussion forum but it isn't shown inside the forum. Same with a thread on heartworm pills by TessaGA.
