Even i set set_bonuses and supremium_flight both to false, i still can flight.

# Should Prudentium+ armor give set bonuses? This does not affect the Supremium Flight option. [default: true]
    B:set_bonuses=false

    # Wearing a full set of Supremium Armor gives flight. [default: true]
    B:supremium_flight=false

I figure it out, i set suprmium_flight=false at server side before, now i set it client side, it's work fine, I'm curious about why control on the client side.....
