Can someone please shed some light on this (new??) parameter? It’s not even mentioned on the documentation and turning it off makes the agent act very strangely (keeps circling around the destination point without ever reaching it).
Thanks in advance.
Sorry for the late reply to your question but given that I suggested Unity add this new NavMeshAgent.autoBreaking feature several months ago, I feel compelled to reply 
Here is a short video explaining NavMeshAgent.autoBreaking.
Thank you so much for putting this together!
