Forum Can't load last thread page

[محروم.كوم]

Hello,
we've got some threads with more than 1 page that have very annoying problem.
You see that there are new messages but when you try to view last post/page it loads the page before it. Users make new posts but they can't see the last page again and they think that their long post is missing. There must be 3-4 new posts so the last page become visible :/

I think there is a mess with deleted post in thread.

How I can fix this?
