I had a giant launch into orbit recently.
I was traveling down a back road with Lydia, and we came upon two Giants. Lydia runs up and starts attacking, at least until she reaches here crouch mode.
My character moved, sneaking to some rock quite a ways above the Giants, so I could snipe at them while Lydia would take them head on.
More than once a Giant would do it's pounding with it's club and to my amazement Lydia would literally fly out of sight! Must be like hundreds of feet in the air. I think it is a physics bug having something to do with my character being so far away from Lydia and the Giant.
It was really kind of funny. Each time, after a while, Lydia would eventually come running in from some place and continue to attack. The fall did not appear to kill her. Maybe because she must have fallen very far from my character.
But this was not just a 30 feet in that are flying. This was hyper flying by maybe hundreds of feet.
.... Another time I watched one send Lydia to the moon. ...
You transparently posted this while I was typing the exact same thing above!!
Glad I'm not the only one to see Lydia launched into space.
