Rules in 16800 don't work?

[blacktraffic]

it's exactly like undeath explained above.
Without the -S slow mode the passwords that are too short (from the dict) are rejected immediately, while the -S mode is slow because it mangles the words with rules already on the host (CPU). This is just a speed tradeoff, a design decision. A known limitation

Wow; I really should have known that given how long I have been messing around with hashcat, and I did not.

I do now - thank you very much!
