Turning off a destructible mesh's collision will still affect navigation around the destructible mesh
This issue is related to [Link Removed]. The workaround for that issue does not apply here (turning on Simulate Physics does not update the navigation when collision is changed)
Navigation around the mesh is still affected by the destructible
Changing the collision of a mesh at runtime updates the navigation in relation to the mesh.
