I'm a retard
I backed up the gpg key before transfering it to a smart card. Then I transferred it to the smart card. But I re-exported the private key to the same file, overwritng the original backup, not knowing the second backup actually just contains a pointer to the private key on the smart card, no wonder the file got smaller

Then I had a uh oh moment, I can't get the private key out of the smart card because that's the point of using a smart card, now if the smart card fails, or I fuck up again, I wouldn't be able to use the private key

So I'm signing this message with the private key on the smart card, revoking it
The new key would be
