The creation rules are as follows:
- If a world exists in settings.ini but has no world.ini, then:
- If the world name is x_nether, create a world.ini with the dimension type "nether".
- If a world called x exists, set it as x_nether's overworld.
- Otherwise set the default world as x_nether's overworld.
- If the world name is x_the_end or x_end, create a world.ini with the dimension type "end".
- If a world called x exists, set it as x_the_end's overworld.
- Otherwise set the default world as x_the_end's overworld.
- If the world name is x (and doesn't end with _the_end, _end or _nether)
- Create a world.ini with a dimension type of "overworld".
- If a world called x_nether exists, set it as x's nether world.
- Otherwise set x's nether world to blank.h
- If a world called x_the_end or x_end exists, set it as x's end world.
- Otherwise set x's nether world to blank.
