I've got some AI tweaks that didn't make it in (tactical combat stuff). I'll ask Charles to look at the auto resolve to see what changed there. I'm not familiar with that code so I can't say why it's doing what it's doing.
The other thing I'm anxious to get in is the XP distribution update which favors more XP when there's more units (0.85 doesn't really reward facing a large army but rather looks at how powerful the top units is).
