did beth change something between patches 1.0 and 1.7 ?
only times a dragon has atatcked a settlement is when i fast traveled to river wood and slow time + thunder bolt quickly solves that problem that dont even get a chance to breath fire
only in falkreath cuz one spawns just to the side of it i could be traveling there on foot and gets attacked i gave up going there (nothing there any way and dark brotherhood just far enough away that if dragon does spawn it wont be able to fly to falkreath and attack stuff)
