Hello! The replacement for the knight costume requires the file mentioned in the title for it to show up properly, but I don't know where to find it as it wasn't in platasp's hair default RAR.
Oh? I suppose that makes sense, I was just assuming that it needs to be downloaded separately since it mentioned requiring a specific file. Still, good to know!
It's in the Clothes folder with the hair default RAR. the helmet and suit are combined into one file.
