Conversion resulted in neutral units

I was just playing a game 1v1, rus vs mongols.

In the middle of a fight the rus player attempted to convert my army, I killed his warrior monk. he had a second one and he attempted a second conversion. I killed him as well but all my army became neutral!

I couldn’t use and my opponent couldn’t use.
I was able to convert the army back to me using my own monk. but wondered if this has been reported before.

This also happened on DauT’s stream yesterday

Thank you @FuluBigilla and @mige1136! I’ll log this so the team can look into it. Appreciate it!
