Retaliation spawning

[Nord]

Hello.
I found a nasty thing:
I created one additional retaliation mission for one specific race and specific research rules.
And i created a race, that never act as retaliation staff.
And then i see both new retaliation missions spawns without all conditions and retaliation missions with that race. :-(
I understand that so this is not monthly generated mission, but one spawned after i shoot down ufos.
So, a question: can i somehow interfere (configure) retaliations, spawned by shooted ufos?

I also looked for the answer to this question. It seems that this will only work if everyone race is assigned to his mission of retribution.
