Its not a bug because its intended to work like that, they have it set for 60 second time out per turn, granted it would be better if they set them to just move period or had scripts that would send them after the player. Personally it seems the encounters are going to be harder and on top of that more difficult, escaping on turn based used to be easy but now raiders take shots to a certain distance/hit percentage. wouldnt be so bad if you were fighting one or two but when you run up on 8 guys with guns your options are fight or die, there is no more running.
*sigh* im trying to explain to you that its not a bug because thats how its intended to work, a bug is something that is malfunctioning and not something that just doesent work the way you want it too so you think its broken.
how do you know? are you a dev? i wouldnt question something thats worked the same way the span of the game.
