I have noticed, multiple times, that when i sometimes switch my weapons around, like switching a sword and a pickaxe around for example, after i have closed my inventory, a minute or 2 later, my weapon shows up on the ground out of no where...i didn\'t drag it out, and i made sure to click an empty spot in my inventory....but it just magically appears from no where on the ground...  This happend once when i was next to a rock, and i had a heck of a time trying to get it back from inside the rock....
