#update_lists is incorrect

[sigerello]

I think that method #update_lists has incorrect behavior. The right way is to update not all lists if some scope was changed, but update the only one that has this scope. If I change position1 in one list I don't need to change position2 in another list on update. What do you think about it?

Yea, that sounds like the behavior it should have. I'll take a look into it, thanks for the heads up!
