Could you explain your issues in more detail? I have been to plenty of topics today with more than 1 page and more than 25 posts. I would also recommend trying a hard refresh (Ctrl + F5) to see if that resolves anything when you encounter a problem.

Threads will display the wrong number of replies (I only figured this out because threads displaying as 0 posts to me got constantly bumped as if I hadn't read them.) When opened, threads will only partially load, leaving the rest inaccessible (hard refresh still reloads them to the exact same point). Basically, the forum is becoming unreadable (only for some topics, I don't know why).
The only way to get around the forum being unreadable is to post a reply, which for some reason allows me to see the posts that are there but not being displayed.
