I've watered the Maray Tree and returned to Hunrath via the Tree portal, and now I need to get the cart to the junkyard and get ready to travel to Mofang. The tunnel I have to travel to get the cart oriented properly is blocked by a huge black boulder. I've tried using the blue beam to destroy it but that doesn't seem to have any effect on it. I suspect that somewhere along the line I've used the wrong portal to get to Hunrath, probably from Kaptar early on, and this has left the tunnel blocked. If so I guess I will have to replay the game from the start.

But just in case, does anyone know something I can do to get that stupid boulder out of the way. Or at least what I did wrong earlier so that I won't run into the same issue next time.


Edit: I figured out how to get the cart heading in the right direction without having to go through the blocked tunnel. I had to blast out an opening on the track leading to Farley's house, and then I was able to get the beam generator pointing forward when I went through the portal to the junkyard.
