Raiders take impossible paths

I’m building on a fairly mountainous map. Raiders are taking paths that should be impossible.
Walls cannot be built right up against rocks or hills, and the raiders just go around. They also travel over terrain that should be far too steep.

Raiders (with a battering ram) went around both ends of the wall in this screenshot.
That should be impossible.
