D'oh!
I should have realized. I didn't know a unit appeared. I had no idea which river was the Karkeh.
Shield violation: when units are exchanged via Civ2Dip utility the unit stays homed. Those "cross-homed" units aren't actually supported by a shield. So we have to account for the shields that would be required to support foreign units listed for our cities. Usually we just move workers to reduce shields below optimum. Which I forgot to do.
