Well, because I don't have time to keep my hands on top of LW. I got a great team back then, when I was starting, but then I was away from the Hive for four or five months because of my surgery and operations. I lost everyone, and the project became abandoned. Now, when I'm back and when I'm ready to finish my map and upload it, I can't get a team of reviewers to help me with suggestions. Sure, there are people that are helping me, and I grow that list with every day. So, now I am waiting for several reviews from the friends that promised me (Hero Reviews, the others covered pretty much everything), and then I will remake the map.
By the way, you should wait to see the new terrain and style before you track a loading screen - you know that the theme might be changed.
