The nails are so broken. There is no back button on the crafting table when crafting nails. When all the nails are created, when you click on the Nails button, the game throws you into the combination lock scene (probably the one in front of the repair station room). The modification of the nails for the hands does not work, it says that the item is missing. If you replace your toenails, then remove Mangle from the table, the game crashes. I'm playing with a save file from a previous update.
