Max world coordinates for character is from -1048534.0 to 1048534.0?

Sorry for poor English

scale: 1000x1000x384
location (centered):
x: -4064500
y: -4064500
z: 98800

Killz: -100000

When character location by X or Y becomes greater than 1048534.0 or less than -1048534.0, it (character) disappears like at Killz.

I use standart first person example project

The solution is uncheck “Enable World Bounds Checks” option in the World Settings
