Sometimes enemy villagers harvesting wood will be visible and in attack range, but will be both untargetable and also unable to be attacked by my units. I don’t know how to consistently reproduce this issue, but I’ve encountered this problem in many of my games dating back to the beginning of the game’s release. The problem is most noticeable when I’m attempting to attack my opponent’s woodline from behind with archers.
I’m hoping that this line from the recent patch notes addresses this issue:
** Fixed an issue where a unit could be visible at the edge of the Fog of War but be unable to be selected or attacks commanded against it.*
