Nukes stinks and they dont like it

[Alknight]

So i'm quite a pacifist so I play in peaceful mode but what a surprise I get the achivement it stinks and they dont like it (Trigger an alien attack by pollution), when I was testing my new nuclear bomb (Well I'm not that pacifist ...). I need your opinion, is this like a feature, or a bug ?
Like this achivement is not disabled in peaceful but the wiki said it's impossible to achive in peaceful.

Well, biters form an attack group when you destroy their homes even in peaceful mode. And internal name for that achievement is "group-attack-achievement". Looks like game engine doesn't consider a reason why that group was formed.
