I was attempting to make a rapier, which broke after a few reforging, upon breaking it turned into a broken tin rapier, which then turned into the standard sword type (first skin upon trying to make one) once I closed and reopened my inventory.

Don't have the materials to replicate it.

There's also a bug where I was trying to make a silver sword, reopened the crafting menu and it said I could craft a sword of a different type of metal (I believe it might have been gold or tin, I can't remember though) and the craft button was highlighted.

Would it also be possible to have an option to check what you need to repair something? It's odd that Dart doesn't know if you need all of the materials, the rod or something else when repairing something when they're a weaponsmith themself.
