@Hexe fight: That’s because she’s behind a “hill”.
@Schrats: seems OPAF not sure if that is intended, but I hope not.
@Zombie Resurrections: I had that too once.
@Legionaires: Polearms can hit over “small” obstacles like a log – you were probably unable to return hits with your banner through the tree (left obstacle).
@Brigand fight. I have absolutely no clue. Forest fights are really weird. I believe both the rock and bush should block his LOS completely and the marksman should not be able to shoot.
