Finished the first dungeon, as it were, killed the gorillas and then go to the area exit. I get a fast travel map that shows the main camp on it, but when I select the "Main Camp" and click to go there, it puts me back into the dungeon that I'm trying to leave. What am I missing here? Anyone else? Bueller?

Not a bug! Got the answer over on the Solasta forum:

That's just for the campaign there, the idea is you can't go back to the main camp because the way back is infested with reaver bugs who will kill you. So the game kind of rail roads you to continue onward rather than go back to the main camp. It's not a bug, it's part of the story.
