I used sort on regs to move all regs from my main pack to a pack inside. If I remember correctly now, we weren't able to do that before, and got an error. This time, it did move the regs, but it deleted everything else in the pack. I will remember for next time, but if we can get that alert put back in so it does not move from the main pack to a pack inside of your main, it may avoid issues in the future.
