The crossbow, after being fired stays in the loaded texture in the hot bar instead of the unloaded texture, but in the inventory It does display the unloaded texture. I also noticed that when you repair the glitched crossbow, it reverts back to the unloaded texture like normal. So, I think it might be that it doesn't show the unloaded texture when it has any damage to the crossbow. All I did when I took the images, was go in and out of the inventory.
Thank you for your report!
