I'm finding a few threads that have pages at the end of the thread with zero posts. So for example, if you look at this thread, note that page 27 has no posts, yet the there is an option to select it.
Tried rebuilding thread cache, but no improvement. I don't have digitalpoint installed. I'm going to try uninstalling a few add-ons that aren't currently enabled. After that, I'll give disabling a try to see if that works.
