I’m encountering an issue with collision interactions between two actors:

  • ​Player Character and ​Enemy Pawn
  • Both use Block collision preset (ECC_WorldDynamic).

Problem:
When the Player stands on top of the Enemy Pawn, continuous compression during movement causes the Player to be unexpectedly ​launched upward (like a “pop-up” effect). No error logs appear.

Reproduction Steps:

  1. Player jumps onto the Enemy Pawn’s head.
  2. Both actors move while maintaining contact (e.g., Pawn walks horizontally).
  3. After 2-3 seconds of compression, the Player is violently propelled upward.
