Training Mastery, Time to War

This doesnt work, I have played many Art of War challenges (maybe 10+ times and getting gold on my challenge time) and even Norman Campaign missions. Im not getting this reward and it is still locked.

Time to War
Complete and Art of War challenge or Norman Campaign mission.

Hey @DafneyAtlas! Thank you for reporting. The only thing I can think that might cause this is completing the Mastery while offline. If you were online when completed, best thing to do is to contact support with your warnings.log file.
