I know that in the lower right corner of Rootinia are borders which are blocked and the players at our arcade had this problem where you just couldn't leave the region, even though everything up to that point had been cleared.
What we did to get into Shantomia was dumb luck, I think; I decided to play the Short Term Memory mission a few times to try to legitimately pass it (it gave me a pass the first time around even though I completely failed the mission and failures every time afterwards).
After a few more tries following the initial attempt, the path opened up. You could give that a try. Not to mention, it's kind of a fun mission. |
