I play this game a lot with my brother, and we farm together a lot. When we get a legendary, usually we dupe it so each of us have one. I had to work a double, but he was off and pretty much farmed all day. He ended up with like 6 or 7 lvl. 50 legendarys in one day! Lucky day right? However, we were distracted during the duping phase, and made a fatal mistake. Basically, they are all gone.
