While executing Work Plan, Yarbo leaves the designated (mapped) boundary and continues running the auger into mulched beds.  Received Error (502) and Error (0) on the app while attempting to manually reposition inside the boundary and begin again. Repeated leaving boundary area.

Yarbo was successful in staying within the initial mapped area.  The area shown where it is leaving the boundary area is an Add-On area.
