So, it's been a really crazy month, and at some point, I went through and deleted some partially finished mods; unfortunately I seem to have deleted the previous lesson work as well, so I can't go back and edit the credit challenges or Lesson 4's NavMesh unless I want to redo the whole series from scratch. As such, and since I had moved on before getting approval to do so, I went ahead and also completed the Non-Release version of the final exam as well as the release option previously posted. Not sure how you want to go about doing credit for these, whatever you feel works best is fine with me :-) If you have any problems with the link I can give you my login info or re-upload here as needed.
Here's the link to the gallery.
