Hey,

A small ticket to inform that it is not possible to transfer an entity to an unloaded & enabled world as the docs says.

(screens from the API)

Indeed, the method Server#getWorld is used but it only targets loaded worlds, so the optional World is always empty and the method transferToWorld wrapped in map is never reached for an unloaded world.

Thank you for reading this issue.
