The bug email address is an auto funnel into our bug tracking system, so you won't get a reply. As for the last target issue, based on your report,
In order to make something your last target it has to be the targeting result of some cursor targeted action...such as using the arms lore skill, using honor, anything that requires you to cursor target a mobile.I then click on my target so they are selected in my current target window (This should make them last target right?).
