Eager, too eager, to start I loaded the new scenario.
Error 1.
Forgot to set Allies to AI and realised this blunder as the scenario started.
Error 2.
Pressed Surrender instead of Quit - so Allies got a victory before I had moved anything.
Rage quit - off to pour a brandy and start again more carefully.
Thanks for the update and new scenario. Back to Stavelot for me.
