The circles are buged as hell. Every time I move them, they end up in mirror position to the position they are supposed to be in. The link is allowed to continue into the second sphere where there is no visible path. It is still possible for me to navigate myself through the skill tree but it is just messy. Also, I cannot experiment with variety of possibilities because of this. I wanna plan my build so I wanna prepared the circles at start. But every time I quit the game, it restarts into original position and my links between the perks are severed.. but they are still active! So, system remembers my choices but screen does not. THAT is a problem.
