This happens quite alot throughout the game.

It would be nice that in the next patch it was fixed. Thanks.

I saw this a LOT when playing the game. I don't think there was a single section with human AI where I didn't see it actually. There was one bit where three or four marines were all stuck inside an open shipping container waking into the closed end. Do you also notice that AI troop's legs tend to flail around a little when walking up stairs as their feet snap to the steps?
