Based on the feedback I'm going to end the game. It's unfortunate we couldn't have it decided on the field of battle but hopefully the files llama sent Illwinter will help in fixing whatever bug caused the problem. It was just bad luck but this type of situation isn't at all common (this is the first game I've been involved with that had a game ending bug).
I also like Nightfall's idea of declaring it a three way tie. Btw Nightfall, as someone who usually plays non-astral glamour nations I share your hatred of mind hunts. When I get unlucky and don't find any indie S mages I know it's going to be painful.
So it looks like it would have ended up with three nations contending for the win, meaning one would have likely been the odd man out and after they were eliminated the final two would fight it out for the win. Rotarr, you were the leader in provinces I think for most of the game so you would have been a logical target. OTOH, it looks like you had a good relationship with Sephorin's Pan so perhaps Nightfall's Abysia would have been targeted. Sephorin seems to have had the best diplomatic options, being able to choose which side to ally with.
Thanks everyone for playing. You're a good group and I'm glad it seemed to have been a fun experience.
