NavMeshAgent gets stuck on the corner of a Box Shape NavMeshObstacle when it is moved with navAgent.Move

AI Navigation Core

-

How to reproduce:

  1. Open the “NavMesh Obstacle Getting Stuck Test.zip“ project
  2. Open the “SampleScene“
  3. Enter Play Mode
  4. Use A/D to rotate the Capsule and W/S to move it along the forward axis
  5. Rub the Capsule against all four sides of the Cube, try going both ways of the wall (try to go past the corner)
  6. Observe the Game view

Actual result: The Capsule gets stuck on one or more of the corners of the Cube
Expected result: The Capsule does not get stuck on any corners

Reproducible in: 6000.2.0a8 (6bc6fbc26ac6), 6000.3.11f1, 6000.4.0b12, 6000.5.0a8
Not reproducible in: 6000.0.70f1, 6000.2.0a7

Reproduced on: Windows 11 Pro (25H2), macOS Tahoe 26.0 (25A353)
Not reproduced on: No other environment tested

Notes:
- The affected corners may be random on different attempts to reproduce
- When going to the corner from the opposite side, the Capsule appears to be pushed forward, as if it were inside the obstacle - likely indicating a faulty obstacle normal calculation
- The behavior is the same among different AI Navigation package versions
- Reproducible in the Player as well
