There are tons of obsolete tickets crowding this system. And you've ironically added to that problem by posting this. But as already stated, this site needs some *heavy* moderation. Get help from the community if neccessary, but please get it sorted. If you look through a few bugs, odds are huge you'll come across something that should have been closed.
Sometimes mods or devs give feedback that a bug is fixed, but leave a comment for the initial reporter to confirm and close. That is frankly pointless and stupid. If it's fixed, close the ticket, and if anyone still has the problem they can post a new one.
And look at this; http://feedback.arma3.com/view.php?id=13739. Why isn't stuff like this just removed. Even if you are entertaining the possibility of dealing with it, it would be so far down the huge stack of other issues priority-wise, that you might as well remove it from the system completely for now.
And don't even get me started on the duplicates...
I honestly don't understand how BIS is able to use this system for anything useful. It's like a wasteland in here, full of dead tickets and orphaned requests. Surely it would be good for the devs as much as anyone if this place was better moderated?
