This is a huge problem, as it just erased all my hard worked on dupes. There is a glitch that makes it so when you save a dupe, it replaces all of the other dupes. This bug has cost me countless hours of work down the drain. I will be uninstalling this addon, and I will never use it again unless this gets fixed. If you couldn't tell by the way i'm writing, i'm pissed. All my hard work, DESTROYED.
