Developer Notes

This is a known restriction of Detour crowd simulation that it uses only a single navmesh, in this case the default one.

Description

Pawns using a DetourCrowdAIController do not appear to be using the correct Nav Agent when attempting to move.

Setting the AI Controller class to a normal AI Controller allows it to complete the same move successfully.

Steps to Reproduce
  1. Open the attached project (contains both 4.15 and 4.16 versions)
  2. Simulate (Notice the AI Character moving to the Target Point successfully)
  3. Open NewBlueprint
  4. Set the AIController Class to DetourCON
  5. Simulate

Result: Character does not move when using a DetourCrowdAIController

Expected: Behavior would be consistent between the two controller types, and the character would use the correct Nav Agent to navigate to the target point's location.
