we can't separate same item in inventory,shift button dont work. 2 healing potions can't put on one and one.
It's working for me, you need to start moving the item with left button, then click (and hold) shift, move the stack to a free slot of your inventory, then stop clicking left. If you still have shift pressed, you'll have a box asking how many items you want. Did it with a bunch of potions to split them in my party.
