How can it be? a bug?

[Hessenfield]

I won the battle, but what has happened?
I have many reports like this, but the last time I lost a lot of Heavy cavalry.
Everything was the same. I believe that an error occurred during the battle and I want this mistake corrected.
these are the reports:

the general was every time the same.

What can you do? this battle turns the war...


Best regards,
Hessenfield v177

2 parts of your cavalry in the battle at 21:47 fled from the battle due to a low morale. You lost more units in this battle because when the army flees from the battlefield, it automatically loses 20% of its remaining troops. In the previous battle at 20:22, the units' morale also dropped below 50 but you had more luck and non of the units fled from the battlefield which prevented bigger losses of the army.
