I am using version 20 and 2015 with the same results. I edit the work plane, rotating it around the z. I then draw some rectangles, but they will not hatch or will not hatch correctly. Some times it will hatch, but the hatching is outside the bounds of the rectangle. If I rotate the rectangle in the x or y, by a small amount like .01 degrees, hatching will work. Then if I put the rotation of the rectangle back to 0, the hatching does not work. I created rectangles before I edited the work plane and they hatch correctly ill regardless of what i am doing with the edited work plane.
