No solution found :( while previously it did find one for this card #35

Hi all,

I've been playing around with NFC cards for a bit and managed to get the keys for a specific card of mine using miLazyCracker: https://github.com/nfc-tools/miLazyCracker/

However, after trying exactly the same attack again on exactly the same NFC card the crypto1_bs tool keeps showing me the message No solution found :(

My log:

And this is basically the loop where it gets stuck in. What could be the problem here?
