As another fairly new player to this "Alpha/Beta", I'd just like to add to the list the one bug I've had the most trouble with. Loading ground missions, and the loss of all points for capturing the UFO. I don't mind taking grievious wounds to my soldiers left and right, I counted a mission where I had 4 below 30% still a success. But having to iron man all the ground missions means if you make a mistake and lose a couple of your squad your left with doing the whole mission over, or losing out on the 100 points for the UFO.. and since everything else is worth so few points it makes it really matter.
