[solved] How to clone Facility Code in an HID card?

So I cloned with

#lf hid read

and then

#lf hid clone ID

Format Lengths are different between the cards, and Facility Codes are also different. Card Number and Tag ID both cloned successfully.

Please help me make a complete clone.

Updating the firmware made this work. Very strange, because I didn't re-clone the card after updating firmware. Just that post-firmware update, it reads both cards' Number, ID, FC, and Format Length as being the same as each other, whereas before, it read my clone as having 37 bit Format Len and a different FC.

The LF signal demodulation/decoding part has changed a lot with the release v3.0.1   

If you think there is a bug somewhere, do feel free to open an issue on GitHub with details information on how to replicate the bad behavior.
