After the update I found it harder to stack cairn stones, when I suddenly realized that now, the held stones also moved as I shifted the camera angle around.
Before the update, holding down the change view button [mouse2] to change the camera angle froze the held stone in place while moving the camera around to get a better bead on how the stones were lining up.
Now, as I hold down [mouse2] and change the camera angle, the rock is also moved along the axis of movement. Which makes it rather useless to change the view.
The minigame was a tad frustrating as it was, but this makes it more or less unbearable.
