Why Do Forum Postings Keep Resetting?

Today, forum posts keep getting listed as “read” even when I haven’t read them. I’m logged in properly, and haven’t messed around with any settings or quick links. Any ideas?

It’s happening to me as well. Best guess is an in-progress or just-completed upgrade to vBulletin has fucked shit up.

Changes to the way read thread info is stored:

I’m getting the opposite - threads I’ve read come up as unread the next time I come by. Very annoying.

Me too!

It reset one last time right after Stusser announced he had changed things back in the other thread and has been fine for me since.
