Cannot directly go to a step

I am encountering an issue when I try to go directly to a step using a url. I append the step to the url like so ?step=step_whatever but it always directs me back to the first step even though the url still shows the requested step. I was using version 7.x-1.5 and it worked fine with this version, so I reverted _msnf_form_step_set_current() to the 7.x-1.5 version and it worked fine.

The reason its directing me to first step is because, in my case, there are no required steps and the if statement checks if the requested step is > the required steps (which is empty).

1 > null == true so it goes into the first required step path.
