Weird definition of "min_y" and "height", which caused I can't fully use all the range defined.

The bug

When I generate a world out of the height range, the game tells me that the valid range of height could be [-2048:2047].

However, when I using min_y=-2048 and height=4096, it says: "min_y + height cannot be higher than: 2047".

So I need to set a lower value for "height", but the value also require a 16 multiplied number. Finally the top Y value of coordinate I can use is 2031, not expected 2047.
