Upgrade to the final 0.5.6 release.
    *docs*
    For the release notes:
    Fedora 7 includes version 0.5.6 of the Nazghul old-school role playing game
        engine and its companion game Haxima. This version is not compatible
        with saved games from previous Nazghul versions, so those with Haxima
        games in progress will need to restart their games after updating to
        Fedora 7.
