Training Stream - Making Game Ready AI, Part 3 - Nov 17, 2015

I’m having a lot of trouble following this tutorial, especially in this video.
Is there any you might be able to provide the project files for this on github or some similar service after each video?
I was doing well until the engine crashed while I was working on a blueprint and when I reopened the project
it wasn’t working properly and I’m not sure how to fix it.

My only option now it to start over from the beginning.
