Sending any unit to attack this Wilding Rider (in my current game) causes that unit to travel to my capitol city instead of attacking it.

Even though my hero is just 1 space away from the Wilding Rider, I am unable to attack it.  My hero (or any of my units) will create a waypoint all the way back to my original city and ignore the Rider all together.

Reloading from a save doesn't fix it.

Trying to attack via the "Attack" command doesn't solve it either.
