Pathfinding not working properly

Hello!
I downloaded before the unity asset and everything is fine, I used the readme to install it but pathfinding has a problem, look at this http://gyazo.com/9a43ca228634405743a72595fc8e1a2e, the capusle tries to go to that point and the lines are inside the cubes. I did everything the tutorial said but it just doesn’t work.
Thanks in advance

Fixed it by increasing Heuristic scale, still thanks, I’m loving this so far and it will speed up my project :slight_smile:
