So I Have Heard that There is Gonna Be A New Spawn. does That Mean Restarting the world If So I Would Like To Use Schematica To Save My Tardis Thank you.

Dont worry, just a new spawn. The rest of the world will still be fine.

Although any tardises which are currently within about 100 - 200 blocks of spawn will be removed.
