Xillix wrote an absolutely great post with a message that seems to be rather disregarded by the comments that followed. Know that the dev team understands how large bugs like this affect the playerbase. While it's unfortunate that these things happen, exploits and bugs shouldn't be a surprise to anyone at this point - no one building this game is a coding one-man-team virtuoso. Mistakes, holes, and flaws are as much a part of the design process as world expansion. This has not been the first exploit of its kind, nor will it be the last. Things like this come with the territory right now, but rest assured that they are not part of the desired package - and therefore fixes (and punishments) are imminent. Of course we don't like cleaning out all the hard work our players put into the game, so trust us that we consider wipes the very last resort. However if the fix must include a money, item, or character wipe, then that was the necessary step in the eyes of the development team. Sometimes good players may end up paying for something a group of cheaters did, and that's quite unlucky and troubling. But it happens, so we must tuck our chins and go on.
To those people who are either saying or thinking that the dev team is sitting back and ignoring problems, you're delusional to a laughable degree, and you're upsetting a very large number of us. So I'm going to be blunt - don't be stupid. We're not omniscient, but we don't sit on La-Z-Boys sipping hot chocolate mochas all day while you guys are running around screaming about the world collapsing. We also can't always give you an immediate answer to a pressing issue; so if you don't receive a "THIS IS OUR PLAN EXACTLY AS OF NOW," don't panic, don't pout, and don't throw things. There is an incredible amount of work being done behind the scenes.
Jeraphon too made good points in this thread - feature development is not always done by our coders. Writing quests and creating items does not always depend on our programmers, nor do art additions. We don't ignore bugs, but we also can't tackle them all at once. We have just one team member to work on the Mac client, for example. Telling us to stop developing quests and fix Mac issues instead doesn't make any sense.
This has been an unfortunate situation, but if you can laugh at it instead of running around flailing your arms, you're going to come out far healthier, because I won't throw things at you.
