Patch 1.6

Well, I understand that everyone has already completed the campaigns, and I have to do it on version 1.6. After completing the missions, I read on our forum how others did it. I noticed some peculiarities. For example, in mission 2-2, when you need to reach the Griffin Necropolis faster than the opponent, the opponent rushes directly to it, defeats the Knight Defender, and the mission is considered lost. In general, it has become more interesting to play. But there is a problem in mission 4-3, "Servant of the Cult." The Demons do not attack after capturing the second castle; they just stand at the edge of the map. I've lost interest in completing the mission. How can I report this bug to the developers?
