I have accidently sorted my bags a few times now.. while trying to discard an item and have noticed something odd that is now occuring. Sometimes while crafting, it will take an item from a stack that is not first in my bags. IE: Making some leather.. have 2 stacks of alumen or black alumen.. one being a half stack, the other being a full stack. The half stack is before the full stack yet it will take from the full stack instead.

Did I screw something up somehow by sorting or is there a possible bug here?
Have reported it.. just incase it is.. but I feel something might be wrong with some setting that got mixed up in the auto sort I didnt mean to do etc.
