I have taken down everything in the first cove area. There is 1 Goblin Hut up high, north of the barrier mountain ridge. I have blasted Dragon Burst at everything even remotely close to the edge. All objects within reach are destroyed. Still the barrier will no go away. Is this a bug?

Edit: This is the second game I have run into this issue. BOTH games: everything within Burst, breath, ball range have been destroyed. I can find no levers, switches, de-activators on any platforms. WTF is the issue with this area?

This seems to be the same issue as described in http://www.larian.com/forums/ubbthreads.php?ubb=showflat&Number=439560#Post439560
