Freeform drag n drop slide locking itself if incomplete when revisiting

Hi Katie,

I have used some "trickery" to make it seamless, as the drag n drop slide doesn't lock itself if it is set to reset its initial state. I would like to note that the drag n drop slide locks itself regardless if the items are revealed one by one or otherwise. It even locks itself if I check "unlimited attempts".

The major issue is that a freeform drag n drop slide locks itself if it is set to resume its saved state, when it should not do so until the quiz is completed. It doesn't matter if the items are revealed one at the time or all there (I used hidden states to hide the following drag items, being revealed after being the prvious is correctly dropped), the drop boxes become disabled when you move around the course with either navigation buttons or the menu. 

That's like starting to fill some questions on paper in a book, going back a few pages before to re-read the lessons again and finding out that you "cannot turn the page" because you cannot keep writing your answers.
