I noticed a bug, I had an army in a village that was recruiting and it got sieged during the enemy turn. The recruitment froze as it is natural. During my turn, I attacked the that was besieging my army and auto-resolved a win. Then my recruitment was unfrozen but I was able to recruit more units even when my recruitment slots were full.
Hope I helped!
P.S. Thank your for the great promotion, I am loving the game!
