I just posted on what became "Page 10 of 9" of the old immigration debate below, but it got lost.
Seems the software isn't coping with threads longer than 9 pages!
I believe it's a minor error with the software that calculates the number of pages, I think at some point it rounds up instead of down (or something to that effect) and gives a wrong page total/number.
I've seen it happen a couple of times before, I'll have to look into it sometime soon.
