I just found a rather small bug that is of no real consequence but figured I'd add it here:
After getting your dragon form and returning to Broken Valley Quarry, the doors to the mine tower are backwards indoors. What I mean is, if you know which one you're planning on going out (e.g. NE door as opposed to the SE door), you'll come out the wrong side. The left door leads to the right exit, the right door leads to the left exit.
lol like I said, of no consequence really but I actually thought about where I was going out because it's easier to go dragon form on the NE door (IMO), and I thought I mistook what door I had exited.
