Aaron from Youtube ARPG channel noticed that too !

I find these too. Usually once i pick them i cannot click on them in the inventory and if i somehow manage to click on them, they remain "glued to the cursor" and i cannot drop them anywhere except the same place i took them from in the inventory. I have to exit to the main menu, re-enter the game and everything is fine. Also sometimes the item looks like a pair of boots for example, except when i hover over them i see a helm...
