NavMeshAgent.stoppingDistance not working

Not sure why this isn’t working.
I have reset Both Unity and and Visual Studio to attempt to fix this. Seems like a bug to me, it’s calculating just fine, but assigning the new float variable to playerNav.stoppingDistance(My NavMeshAgent) seems to not work. Any Idea’s ? Maybe I should Update to the newest version of Unity(Currently running 2018.2.18f)

Any Ideas would be super helpful!
Thank you !

Hello.

You are using a negative value for a distance. Unity reduces it to 0.

Bye!
