Item Pickups are not Sorted Correctly

[rolandoislas]

When multiple items are picked up at once, sorting behavior is strange.

Steps to reproduce (There is likely more ways to reproduce this.) :

• Fill all slots, which is easiest with one item, except for one row and two slots on another.
• Drop 11 items that will not stack with each other or the contents of the inventory.
• Do a little dance.
• Pick up the items and watch the sorting fail.
