After taking multiple crossbows from my chest, I wanted to empty the arrows from them by randomly firing them. After I shot an arrow, the crossbow in my hand became unloaded, but in my hot bar it still appeared loaded. I opened my inventory and swapped the one I had just fired with a loaded one and fired that one as well, which also appeared loaded in my hot bar after firing. When I opened my inventory, the one I previously shot now appeared as unloaded, but the one I just shot was still loaded. When I opened the chest to put them back, my hot bar disappears for a moment as normal while opening a chest. Once it came back the cross bow with the incorrect loaded icon was now unloaded as it should be. It appears as if the hot bar does not update properly when I fire crossbows.
