well there is that bug when in the stats menu, with the help of speed you can get literaly infinit stanima points. I know taht the stanima is ultimatly useless but i gave myself 100 points to every stat and nothing happened. I think it would be a funny secret achivment if you gave yourself 100 points to every stats. And here how its work. When you click to the upright arrow it wont stop at 10 so u can go up to infinity if you want to. Then if you click the downleft arrow u get the same amaunt of points back. Btw this was my first witcher game what i ever played
