Woo boy! Ok, so, after a bit of experimenting, I ditched my old plan and just blew through KaraQuest on another file so I could find and modify the right flags on my main Save. From what I can tell, it worked! Though there are apparently a few flags or whatever I couldn't modify, so my codec states the I both distracted Shade and defeated Kara with her. Oh well! I guess I'll find out if it all worked out when(if) Savin makes some more Kara content.
