Multiplayer, on huge map, client can not see others.( or some seconds and others auto destroy)

When i come to test with default “Third Person” project of Unreal Engine, scale the floor 1000 times. I set NetworkPlayerStart ( Startposition ) to (X=1905264.250000,Y=952500.000000,Z=688.029175). I’ve set “World bound check” to false and set Numbers of Players to “2”.

Now, my Player can not see others. But if NetworkPlayerStart is near (0,0,0), everything is OK.

If you change NetworkPlayerStart location X to aprox ~1676000.25 cm, you can see that other players display in some seconds then be destroyed.

Sorry for multi posts, the first time i go to forum. Thanks.

Could you help me?
Thanks in advance.
