We have a minecraft realm that we've been playing on for a few weeks and recently discovered that the admin when he made the world did not generate structures.
We obviously want to have structures on and dont want to lose all our buildings. Since we are in 1.15.1 we can't use MCEDIT to copy them over. Basically what we are trying to do at this point is back up our world as a single player world, generate a new world with structures by the same SEED then copy the structures over to that world and restore that one.
Is there a good way to save the structures in large-areas? Entire islands, and a few places in the nether for example.
