I played maybe 12 levels on Facebook and the next time I logged in I was at level 44. I didn't play all the levels between, and want to, but I can't scroll back.
Scrolling with the mouse doesn't work in the new Farm Heroes, what you need to do is click and hold on the background and drag backward or forwards depending where in the saga you need to go to.
