There are 2 ways to assign a texture to an item:

• Create the texture via the Textures submenu and select that texture while creating the item
• Create the texture while creating the item (the Load texture button)

When editing a regular item or tool, clicking Load texture will take the user to a menu where he can create a regular texture. When editing a bow, clicking Load texture will instead take the user to a menu where he can create a bow texture. When editing a crossbow, clicking it will take the user to a menu where he can create regular texture, but this is not desired: he should instead be taken to a menu where he can create a crossbow texture.
