Affect navigation

Hi all. Im confused. No progress in my issue.

  1. How can i disable affect navigation on my pawn in realtime? I need to disable it becouse my pawn always stucks in his own affect navigation radius when moving.

  2. And why doesn’t the NavModifierComponent update its location like said here:

    or how can i move it?
