Ran into a deadlock situation on my first run of the tutorial. When exploring the east I moved to combine my recruited champion with my sovereign. Game stalled with the Windows 7 "wait" cursor right at the point when the animation shows two images of the champion (alongside the sovereign) and is about to fade the center image. The music kept playing.
Game did not crash to desktop so no error report was generated for me to submit :/. The error did not occur on my second game that I am running now.
Game looks and feels better than WoM so far - all of 10 turns or so in.
Let me know if there is further information I can provide.
