Hashcat doesn’t write to output file

[penguinkeeper]

1) Hashcat uses something called a "potfile", which means you only crack new hashes and don't have to keep cracking the same hashes that you have already cracked. To see the 2 recovered, you can either use "--potfile-disable" in your existing command to disable the potfile and re-crack the 2 hashes or "--show" to just get the data from your potfile.

2) You seem to be using an older version, I'm not sure what you're on but updating to 6.2.6 is probably a good idea. It won't solve your issue here, though
