Miguel,
When I posted about the Hudson River thread, the thread was 101 pages long (apparently), and page 98 didn't contain the final post. I had only noticed it as the thread had recently come back to the top of the pile due to someone posting something on it - yet I couldn't read it as it was 3 pages past the limit of where I could access. I think there's probably some dodgy indexing of thread posts going on in the database?
