I started a new game with revision 5215 (i.e. with Koshling's latest AI changes), using the same settings as before (Alexander, Large/Epic, Immortal to Diety). The result? An unmet AI finished Sedentary Lifestyle on Turn 157, one turn before I would finish it. Well played, AI - and well done, Koshling Koshling, here is the Turn 157 savegame file & AI logs, in case there is anything else in them that might be useful.
