I didn't even recognize Haven as the Haven from Origins, you know, where you're running from crazy cultists....Lol.
Redcliffe to me is more different. The Windmill that had the secret entrance used to overlook an open area, it wasn't surrounded by a hill. The blacksmith shop is relatively in the same area but the chantry isn't, and the village where their houses were is also different, they don't seem to have houses anymore. When you do the quest to defend Redcliffe in Origins, the entrance from down the hill is the same, which is how I gauged where the chantry and tavern should have been but they've both moved locations. It confuzzles me!
