Lot of people have asked a fix for this in the past cause it gets quite tedious when it happens.

The "Sort" option in your own/retainers bags is right next to the "Split" option. When you accidentally press the other, all hell breaks lose (assuming you don't use the sort option). Can we either move the sort option on the actual headline of the bag? Or better yet, can we have a confirmation button to sort our stuff, really of all things to put a confirmation button, this should really be one of them >_<
