Does landscape distance affect character possession?

Hi, I spent hours figuring out why I cant possess my character in third person default mode.
I found out my landscape was quite far away down positioned.

  1. When a character stands on a plane Z-pos:0 everthing is fine.
  2. When a character is placed above plane - it falls at first and after I loose possession
  3. When a character stands on a plane Z-pos:-2000 I have no possession at all.

My project game mode is default “ThirdPersonGameMode”

Default pawn class: “ThirdPersonCharacter”

World override: Not overriden.

What is going on here? The character dies and gets destroyed? Is it possible to adjust these behaviors?
Thanks,
