When I finished my first campaign map (Epilogue 1) with Hero rating (that Queen icon), I received 2 achievements. One says "finish one campaign map with at least Aspirant rating" and another same expect for Veteran rating. I have checked the achievement section and realized there are achievements for Champion and Hero rating as well.
I kept playing and completed Epilogue 1 and Stronghold 1 both with Hero rating again. Still I could not receive "finish a campaign map with Champion / Hero rating" achievement. Is there some kind of bug here, not recognizing my map rating?
