        Seems this actually was removed on OSI somewhere between the original bug report and now.
        We will call it ML, until we can get better information. I suspect it was on the OSI TC when
        originally it taken out of RunUO, and not implemented on OSIs production shards until more
        recently.  Either way, this is, or was, accurate OSI behavior, and just entirely
        removing it was incorrect.  OSI followers were distracted by being attacked well into
        AoS, at very least.
