I have set the map of the kingdom now to 2000×2000 instead of 4000×4000. As a reference, the normal world is 3000×3000 blocks large. Why? I do not want to be forced to start a new map when 1.8 comes out. If we restrict our space usage a bit and stay within reasonable bounds, we can generate the map beyond the current limits once the 1.8 map feautures are out and integrate them into the kingdom.
In the case that the 1.8 features are so different from what we have right now that they would be better used in a new map anyhow, we can still create one. I do not want to ruin the fact that we can do the same on fewer maps by already now expanding unreasonably far into that map.
I will see that I can delete the areas that were already explored but beyond the 2000×2000 border so they can be generated newly once 1.8 comes out.
