Well, you'll have to back-up your moons first. Get iExplorer (I don't even remember where I found it anymore), and connect your iPad (or whatever) and find the files inside the mooncraft/lunacraft app. For moon A, there should be files like "Documents/0_-128_-128.dat", "Documents/0_-128_-128.hm", "Documents/0_-128_-128.mw", etc. plus one called "Documents/0_game.dat". And another set of files for moon B with the 0 changed to 1. Save them all on your hard drive (this might use a lot of space!). Then if you get terrain-regen'd, you can copy the files back, but you'll also lose anything else you did in the game.
