if I create an ammo crate via config file containing a custom textured vest, when you open the ammo crate in game it will pop up with an error saying an icon texture is missing.
Despite the error, the item is listed in the ammo crate but without an icon and you cannot select the item or wear it.
If I try dropping the vest on the ground it doesn't seem to do anything but when you step away from the crate you can see a default textured vest on the ground which you cannot pick up
I found if I add default A3 uniforms and vests to my custom ammo crate they work fine and I can equip etc without error. Also tested with other mods and I get the same results
