can't teleport to certain places, navmesh, collision are correct

I cannot teleport to certain places in my map (marked in the red box). When I’m at the place that I cannot teleport, my controller shows a beam perpendicular to the ground. I have done the following trouble shooting:

  • check nav mesh location and scale
  • check navigation
  • check collision
  • check whether it’s because of level streaming, I merged all the levels
    into one but the problem is still
