I noticed this when I was PvP-ing with some friends. As you might have expect I chose the crossbow as my weapon of choice. When playing I noticed that when I fired the crossbow it showed that I still had an arrow loaded and it was ready to fire but when I took the shot it started doing the reloading animation proving so that when a crossbow is fired it displays the loaded image on the player hotbar. This bug needs to be fixed because this can really confuse a player if his/her crossbow it truly ready to fire
