Game Object not properly setting

So I'm working on an RTS game, currently working on the AI for resource gathering. I'm trying to set the active resource node on the player's right click. For some reason, it isn't setting. Here is the rightClick method, where I'm attempting to set the active node.

Code (CSharp):

1. public void RightClick()
2.     {
3.         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
4.         RaycastHit hit;
5.  
6.         if(Physics.Raycast(ray, out hit, 100))
7.         {
8.             if(hit.collider.tag == "Ground")
9.             {
10.                 agent.destination = hit.point;
11.                 Debug.Log("Moving");
12.                 task = TaskList.Moving;
13.             }
14.             else if(hit.collider.tag == "Resource")
15.             {
16.                 agent.destination = hit.collider.gameObject.transform.position;
17.                 Debug.Log("Harvesting");
18.                 task = TaskList.Gathering;
19.                 targetNode = hit.collider.gameObject;
20.             }
21.         }
22.     }

If you need more insight into what is happening in the script, here is the full script:

RayCast only returns the first collider. What if it’s the own player? Better use RayCastAll, and make sure you process all collider instead of making assumptions that there only ever can be two.

 

I get what you're saying, but then shouldn't some collider still return as the targetNode? I'm getting nothing in return, while the target of the gatherer is set correctly to the node with Nav Mesh Agent, that same collider isnt being returned to the target node

 

So I still can't seem to figure this out. Every available option I've tried has used the same methods, but mine isn't working.
