Previous page problem

This is pasted from my RHP club forum with minor changes:

“The question I have (as an iPad user) is why sometimes when I open a RHP club forum thread it opens on the page *before* the current page... and I wonder if this is causing replies to the wrong (non-current) post (edit: it just did it again when I posted this —.posted correctly, but then opened on the previous page — l’ll call it the previous page problem).”
