I'm not attached to anything in the the current temp world, so I say go for it when there's a stable 1.9 release. The Eastern Tower was really just a small test for a possible project in the future. Turns out it was stupidly difficult for being so small, so much so that I may have to rethink or scrap the future project.
[edit]: although, give us a heads-up when the change might occur. I'd like to take some pics for reference just in case.
[edit2]: Got 'em. Delete away.
