Weird issue with transforms, use of Invoke, and NavMeshAgents

Hi,

I have noticed a weird issue (bug, perhaps?) when getting the 'position' of an object's transform within an Invoke() routine. Here is some sample code that demonstrates the problem:

Code (CSharp):

1.     void TestMe()
2.     {
3.         Debug.Log(transform.position);
4.     }
5.  
6.     // Update is called once per frame
7.     void Update()
8.     {
9.         if (Input.GetMouseButtonDown(0))
10.         {
11.             Debug.Log(transform.position);
12.             Invoke("TestMe", 1.8f);
13.         }
14.  
15.         if (Input.GetMouseButtonDown(1))
16.         {
17.             Debug.Log(transform.position);
18.             StartCoroutine("COR");
19.         }
20.     }
21.  
22.     private IEnumerator COR()
23.     {
24.         yield return new WaitForSeconds(1.8f);
25.         Debug.Log(transform.position);
26.     }
27. }

The output from the "TestMe" function shows a wildly different Y position for my object's transform than the output from "COR". I thought Coroutines and Invoke were similar if not the same, but there is clearly a difference here.

However, this is only an issue when there is an active NavMeshAgent on the object. With this component disabled, the Y positions are identical.

Is this a bug, or some weird side effect of using Invoke?

I am on Unity 5.3.1f1. Thanks
