I think there's a serious issue with changes made in v4.1.0 here. The changes have effectively killed the ability of having a specified number of top layers for all location but the very top of the part.
Here's a vertically cut slice using v4.0.1 showing five solid layers for every top layer:
Note the multiple layers under every layer that forms the sloping top surface.
Here's the same thing with v4.1.0:
Note that only the highest top layer has the specified number of solid top layers. Virtually every other layer that forms the top skin has NO solid layers under it....BAD!
