Typing http://area51.stackexchange.com/proposals/1338/gaming/3311#3311 into the address bar just sends me to the first page. It's as though the "3311#3311" isn't there.
It doesn't appear to be browser specific:
Looks like "Newest" is the only page that functions reliably - the rest will work only when the question linked to happens to sort on the first page. – Shog9 (in a comment below)
Changing sorting to newest and trying the link again always works when I've tried it.
