MifareNested collected nonces in 'while (target_nt[i] == 0)' with no attempt counter. When the tag NAKs the nested authentication the loop re-sent the identical frame forever, so the client's 2s wait expired and autopwn returned PM3_ETIMEOUT — throwing away every key recovered up to that point. Reported on a card whose sector 16 refuses the standard MFC EV1 keys: 32 keys cracked, nothing saved. A NAK is a refusal, not a glitch, so the device now gives up on it and reports PM3_EWRONGANSWER. autopwn names the sector it skipped and carries on, and a timeout falls through to the key table and the dump whenever anything was recovered.
