AI doesn't seem to love using air strike from both right and left side. I haven't noticed such thing in 0.9.9 but since the AI-players use air strike rarely, it's probably there too. This isn't a bug or some major problem. Just needs to be improved a little bit if I'm not mistaken...Let me explain with an image:

The first image shows a correct air strike which anyone of use will apply in this situation. The second image shows what the AI does (at least by me and of course when I've noticed that ). It strikes from the wrong side. A side from which the effect of the attack is minimum and some times - none.

If anyone has noticed airstrike from the right side then I'm wrong. Today this situation happened to me twice. Both times the air strike was from left and my hedgehog was on the right side of the hill. My hedgehog was of course not harmed by this.
