Skid steering in reverse

I just began evaluating ArduRover for a possible boat application. Before selecting hardware, I have chosen to user apmplanner2 (2.0.24), SITL, and MAVProxy to learn about the rover software. Just to confirm, I am running 3.1.0 software. I created a mission with several waypoints, the last being a final destination. Before the last waypoint, I inserted a DO_SET_REVERSE command.

When I run the mission with the default rover.parm file, the mission runs fine. When I run it with the rover-skid.parm file, it arrives and the next to last WP, switches to reverse, orients the rover properly and then crashes before proceeding to the final waypoint,

As far as I can tell, the parm files only differ in the value of SKID_STEER_OUT=1.

Picture a rover navigating through a parking lot, arriving at a WP in front of a parking spot, changing to reverse and backing into the parking spot as the final WP.

I tried reducing the speed to 0 before the DO_SET_REVERSE, and back up to speed after. It stilled crashed.

Am I missing something fundamental? Still learning about the logs, so input would be appreciated.
