I've noticed some poor accuracy in the little read/new icon to the left of each forum on the homepage. I've seen a 'NEW' message for the assembly forum quite a few times over the past few weeks, only to find there were no new posts there. AFAIK, ususally after visiting the forum, the icon on the homepage tells me I've read everything in the forum, as it should, but in the next few days, it says 'NEW' again when indeed there are no new topics.
Is this a known problem?
