For people having issues with the IsOnPath method always returning false.

I came across this issue with the code used in the video, so if you come across this issue. Here's an alternative:

        public bool IsOnPath(MapLocation mapLocation)
        {
            foreach (var loc in pathLocations)
            {
                if (mapLocation.X == loc.X && mapLocation.Y == loc.Y)
                {
                    return true;
                }
            }

            return false;
        }

What it does is it loops over every path location and checks if the given map location's X and Y coordinates are equal to the path location's coordinates. If those match, the method returns true and breaks the loop. If the loop finishes without a single match, it will reach the return false statement, and thus return false.
