Some times you can fly over impassible terrain, sometimes you can not. this is is instance where impassible terrain is inconstant on the same map. SotM could fly over the hatch sqaures, but AoC could not fly over the bush. I on the level nora glades you can not fly over any hatch spaces. what is the difference between the bush in the picture and the hatched spaces? Why is there a difference? Why can you fly over some impassible terrain and not others.
If you look closely, you can see it is technically not impassable terrain but out of the map boundary. (Not sure if that is true, picture doesn't show all) . But that would be my guess.
Crisscross hatch marks or dot dashed hatch marks for all non-accessible terrain or map boundary. Hatch for impassible terrain. (When viewing the grid [G] x2)
