I'm really concerned with some of the issues in the forge (pieces not lining up, precision mode, invisible wall on the Tower, 3 Story, Erosion's lighting, etc.) and I was wondering if Certain Affinity or 343 have said anything about a patch being in the works. I have Ghost Town mostly remade on Erosion, but I caught the lighting glitch, and I can't finish it without the map looking like poop. And it's impossible to make a Lockout remake right now without having to build the BR Tower by hand. It's just... UGH!!! PLEASE PATCH THIS CRAP 343/CA!!!!! Edit: Crap, just noticed there was another thread right on the front page about the same thing... I'm embarrassed now. Uh, feel free to delete this post.
I really would like to know as well. A friend and I were trying to figure out if there were some type of 'trigger' for objects not lining up exactly as you've saved them. We think that it may be a "magnets" issue. Anything that I've 'freehanded' the object without using magnets, the object seems to maintain its placement. It may also be a rotation angle issue as well, I try not to use the angling so I haven't tested to see if the object maintains its placement. I don't know if freehanding the object is your forte or not, but this may be the only quick solution until they fix the forging issues.
