The problem arose when I created a separate script to handle mouse to handle Mouse input. The idea was to limit the expense of ray casting by only calling a raycast when a agent was selected.
The selection process works however before an agent moves to its desired location it insists go to a specific area of the graph.
The (Lets call it first waypoint) location varies with the size of the graph.
This is the AI script attahced to each agent (Some function have been commented out)

If Anyone has any suggestion to this problem that would be fantastic. Or at least why it doesn’t work or why it can’t work.
If there are any other approaches people would try to implement when managing selection of multiple agents.
Feel free to ask any questions if you feel I have no provided enough information. It wouldn’t let me post more than 2 images due to being a new member so I pasted the code in text.
All the best James.
