Amnesia: Through the Portal (2.0 Expansion Released)

[Ghostflame]

Ok, at the risk of sounding like a derp, I picked up the master orb but still couldn't get back through the tunnel, it was an invisible wall. If this is any reason, maybe there's is a trigger on the stairs on the way down? Because I was a boss and jumped down from the top. But please, what do I do?

EDIT: I grabbed the fix, because I already had it, maybe it doesn't like that? I don't know.
