1)  Set a bag to collect only Squire weapons and armor.  I also set mine to collect only gear level Powerful or higher.

2)  For another bag to the right of the first bag, set it to collect only Apprentice weapons and gear (Powerful or higher).

3)  Play a game and pick up some loot.

4)  Look at your bags and notice that the Squire bag is collecting Apprentice weapons incorrectly.

I also have bags that collect Monk and Huntress gear/weapons, and their weapons correctly go into those bags (and not the Squire bag to their left).
