I wanted to provide some comments on enemy warnings. None of the following are consistent, though.
Sometimes I will be notified if an enemy is passing my buildings, like a random wolf running by but not attacking.
Sometimes I will be notified when a large enemy attacks a gate.
Sometimes an enemy can break two gates and kill a person before I am warned. (One time they were on a third door)
Personally I would like to be notified when a new enemy/group appears on the map, and then again when it actually starts attacking, because:
not all enemies attack
gives the opportunity to attack proactively
minor enemies accumulating on the screen weighs on performance.
I use the latest alphas, btw.
Thanks, and keep up the great work!
