FBR OLD BIRTH CERTIFICATE HELP

I submitted my FBR application back in August and now I’m stressing a little bit! I saw someone say that they re ordered there Grandfathers birth certificate because it looked a bit worse for wear. Mine wasn’t in the best condition but I submitted it because it was all I had. Has anyone else submitted a very rough birth certificate?? Also do you think it will make a difference if it’s old, surely they can still verify it?
