For now there is only function to detect attack and create Bot Report with additional information. Those infos are: slowest unit, arrival time, travel time, distance, etc. You need only to select detection interval in "Villages->Attack detection" tab. Then check if there is new report in "Reports" tab. Just open it to see info about incomming attack. This system will be extended in future. Attack avoidance, attack interception(4 nobles coming, send support from other village with arrival time between 1st and 2nd attack), and other functions will be added.
