The Sspecified thread does not exist?

[RocketFoot]

Hi guys!  I have a minor problem that's giving me trouble tracking down.  Some of my members are reporting that they will get an error that says "Specified thread does not exist" when they click on a large thread but usually from the thread's multipage numbers.  (Like clicking on page [3] of a thread from the forum index)  Do you have any ideas what could cause this and how can I fix it?  It's minor but really annoying.  I remember Yumi helping me onetime with a multipage problem.  I'm not sure if this is related or not.  It was this issue:
