DB/SAI: Jenny (Load'er UP)

Ok so found I needed to rescript this to as had not noticed there was already a script on Fezzix Geartwist for this quest, this sai has got same flaws as cpp version had, when npc gets attacked and evades looses crates aura (another example of the thing with auras getting removed at evade causing problems),
