Oh yes, just saw the appstore update. The Treent of Life can be expanded to at lvl 20 (so can the other animal, but it doesn't give me the option to straight up expand to it. I suppose I would need to expand adjacent to it, first.)
But, uh, yikes!
10 million?? Is that just because I'm level 40 or because they're being annoying about this? A level 20 sure as hell ain't gonna have that cash. (And I've actually just hit level 40 recently, so I'm not really at the point where I have millions lying around.) Guess I'll have to save up...
