It seems this glitch also happens when crafting an improvised explosive from a Protective case. Besides the fact that it will not use any of the electrical repair kit, It will create an improvised explosive without deleting the protector case. Glitch happens when interacting both ways (protector case onto repair kit and vice versa). Meaning you can craft an umlimited amount of improvised explosive cases.
Also happens when crafting armbands from a raincoat, Raincoat will stay on the floor after having created the armbands. (important to notice that it is still possible to wear or interact with the raincoat after crafting armbands, meaning this is not just a visual glitch.)
