So i have a server whom we changed the world spawn to a different coordinates, but the nether and end maps when loaded are centered around the old world coords is there a way to center the map around a specific coordinate?

If you want to have a look at map you can check https://map.vanillabois.ga

Currently no, it only uses the spawn location. Each world has it's own spawn location, so by adjusting the nether/end spawn you can move the center.

How do we edit the nether/end spawn? cause /spawnpoint commands doesnt do anything in end or nether

/setworldspawn, /spawnpoint changes individual player spawns
