Causing a Nav Mesh update, such as by moving an actor into the NavMesh that will create a hole, seems to be breaking Nav Link Proxies by preventing characters from being able to use them.

Steps to Reproduce
  1. Open the attached project
  2. Simulate
  3. Stop Simulate
  4. Delete MoveableActor from the scene
  5. Simulate

Result: When MoveableActor affects the NavMesh and causes the hole to appear, the character is no longer able to use the Nav Link

Expected: The object affecting the NavMesh would not break the Nav Link and the character would be able to move back and forth as it would if MovableActor was not in the scene.
