Since the file has been mostly unthouched since the release of 1.7.2 and the world generated in 1.6.2, there were a few block updates needed along with a refurbish on the style of building that the mycraft build team had at the time. (In other words, we weren't the best builders back then). Now since this is only a refurbish and a little update, i wont be changing the horrid style the buildings were made in, i will only tweak them to look a bit Three new skyscrapers, two new roads, a new parkinglot and one restruant were added in this update, aside from the general detail fixes.
Enjoy and let me know how the solo refurbishment is doing so far.
