There have been several times in explore where I've had to give up on a mission purely because the ghost tells me to go one way and then the opposite way once I got to that point, leading me in a circle. Perhaps a bit adjusting the way the mission guidance system worked could fix this, maybe a second way point right on the destination, like a direct point A to point B path, along with the current one. I'm up for anyone else's suggestions as well.

I free roamed in explore. I didn't really do a whole lot of the mini missions.
