Thanks guys for the great info here. Can someone tell me which part of a familiars code dictate the signs? I would use the editors, but they either produce corrupted saves or fail to load correctly(it said that my mitey had a double planet sign when it was just a sun, among other things)...
if they get permission from 4j (the studio who helped put minecraft on consoles), they could put the console edition tutorial worlds in the game, as seeds
and i mean all of them (if not, maybe a few highlights, like TU1, TU31, and TU69)
