Thread Subscription Issue

[Gardocki]

I subscribe automatically to all threads I post in, because it's easier to to see when someone posts something new in my User CP. About a month ago and again tonight, three threads with no new posts have popped up in my User CP saying there are new posts in the threads, but there are none. I assumed the first time it happened it was just a bug, but it's happening again. It's not a deal breaker for the site, just annoying when I come and see there's supposed to be new posts but there's not.
