For 1.3. They have new items that can be mined from world. Since older world wont have those items I think the map would have to be reset. But I will be looking for possibility of migrating map if it was/would be possible.
Not sure you can do that, Nomy. When it went from 1.1 to 1.2 all the worlds had to be re-jiggered for 1.2, unless they've changed it and it is possible. Could be worth a try.
Chill your box now, mate. With all this talk of updates, Minecraft just seems less and less like... Minecraft. Like I've said before, I wish it was old 1.4 again.
Surly the top chunk of the map ( where most of the buildings are) could be imported somehow? Looking forward to the update tho
Well if this cant happen, I guess that's how they designed it and we will start with a new world. So I think we should expect the world resets on major updates.
If you don't know Nomy, you can copy/paste from world to world, don't know if that helps you but I know all those commands and can give them to you. Although I'm not sure if it will crash the server when it's that many buildings
there is also the problem that wood blocks and wood planks will no longer exist under those ID's and named. The will not be individual, for each tree type. Also the introduction of coco plants means that you can't just copy the few top layers...
