I just started noticing that a lot of times when u click on the arrow to go to the last post of a thread that it sends you to a page that says "No Thread specified. If you followed a valid link, please notify the administrator". It's happened in a few different sections and every thread I tried in this section.

 

It seems to be an issue with threads that haven't had any activity prior to the vB upgrade. (i.e threads that were created prior to 12/22 and haven't had any posts afterward). Well see what we can do.

 

ah cool. I think I saw it a lot the day of the upgrade, but a lot less since then which would make sense if it's just because the posts happened before the upgrade.
