At least they got to it before the Playstation 4 and Xbox One release. Zenimax finally removed a duplication bug in The Elder Scrolls Online that allowed players to create endless multiples of items and make millions.
The bug was so basic that some players found it completely by accident. When you entered an item into the Guild Bank, the bug would allow you to keep taking that item out over and over again, and it would still be in there.
So, Zenimax has removed the exploit and laid down the law. When they figure out who exploited the bug, these players will be permabanned. We hope none of you were crazy enough to abuse it thinking Zenimax would not get around to it.
