you're asking to fix months of code on a forum that may be as messily coded as the game it's designed for. as much as it sucks, it's more than likely that it's easier to remake the forums entirely for the new game, than it is to rework the way the current forums work. for all i know, it could take weeks for the problem to be solved, or it could take a couple days, or even just a few hours. but during that time, while the devs fix the problem and update the site, the forums will probably be down for maintenance. meaning everyone who wants to access the forums, can't. like i said before, easier to wait for a new forum, than try to rework the way the old one works.
i know it sucks, and it's an annoyance. but messing with the entire site to fix a problem that a small percentage of the community has a problem with is probably fairly low on the dev's list of things to do. but i can't speak for the developers, and i can't say what exactly the problem is, because i don't know. if it gets fixed, it gets fixed. until then, we just have to sit tight and hope something will come of it
