So I realize (late) that I've hit the Hertwig Van Hal glitch where his quests don't trigger/progress. His bonus is that reinforcements join the final battle, however, when I fight the final battle and lose, the battle never resolves because it looks like the computer is registering that the reinforcements haven't been defeated. However they are never redeployed either, so i just have to concede the battle. And when I look at the post battle report, the reinforcements are included in the report as if they were deployed.
Does anyone know how to fix this glitch without having to just reload to try and get Van Hal's quest to trigger properly?
