Bug: tutorial misision ends prematurely

[gameplayer878]

In Flight Tutorial 8 - AAW 6 - Advance Combat, when i shoot down incoming 2x Mig 23ML Flogger and 2x Mig 25P Foxbat, as soon as last Mig 25p goes down, my tutorial ends with minor success end result. I've tried again and again to same result. Not sure if I'm doing something wrong or tutorial is broken. I've attached my save file. To reproduce shoot down incoming jets with already in flight f16 and when 4th aircraft goes down it will end. Although i've double checked expenditure and losses, i do not loose any air unit but somehow it ends prematurely. Normally it happens when you incur loss of an aircraft, but not sure how its happening here.
