You can combine an item with itself, resulting in a crash.
When moving an item in the inventory (for example, a stick), you can drop it on itself. This would start the crafting process (2 stick would create a staff), but since there is only one item, you can't craft and the game will crash.

After crash, the XP bar becomes full, even though I am not even close to level up.
