I've seen some similarly bizarre pathfinding with vehicles in close quarters.
Earlier this week I repeatedly tried to send a M20 through a reasonably wide gap between a building and a hedge. For some reason the vehicle insisted on turning left towards the building when it looked like it could have gone straight or since there was about 1/2 a vehicle width clear on the right a right turn would have been logical…
Playing real-time I managed to, 1 foot at a time, with a dozen or more individual face and move commands, get it through the gap.
I then gave it a "quick" command forward across an open field, then 90 degrees left towards a hedge line. It turned right at the waypoint and went about 20ft towards a fenced opening in a hedge on the other side of the field. It then tried to turn around 1/2 way across the fence and continue in the correct direction.
So, I guess not just tight quarters!
