Most likely it's a program bug. When someone edits a pos to shorten it, it reduces the amount of pages. Unfortunately the string that puts posts onto a page is seperate from the one that makes new pages, and the one doesn't tell the other when a post is shortened, so the second program keeps making pages as if all the posts were original length.

Don't quite think so. The code would generate a new page every 20 posts regardless of length. The fact that it's showing up with 82 out of 81 pages means that some posts were deleted and the orders got muddled up, but it remains to recognise them.
