I tried doing a search but putting 'Emerald" and '1.3" into search got me hundreds of results, 99% of which I don't think relates to what I'm asking..so if its been started as a topic, forgive me. Has anyone thought of, or working on a relatively simple way to 'update' your MP map to 1.3 for the new blocks? My long time players aren't really fond of a 'new world' again so soon since the 256 height change. I mean Ive done it before the "well we have to because of X being changed" over the last few years..but every time we lose a few dozen people that don't feel like loosing everything they made. I could do the world edit select HUGE areas and replace stone with a % of the new blocks..but that's not really viable on a whole map scale. Expanding the borders of the world WOULD work also...but then Id have a week of terraform to get the new chunks to match the edge of the old terrain gen...no less work than the WorldEdit idea really. Anyone thought this out and came up with a trick?
