This only happens if you never teleported before. Also, IIRC, the room is
protected against normal teleports.

If the first is your case, you can do a normal teleport, and the three-nodes
system will start working again.

I don't think you can do a normal gameplay without teleporting even once (say
about patience!), so I'm postponing this issue.
(PS. The gate is open at some point on the dialog. Also, if you think this is a
relevant, active bug, please move status again to open and I'll take a closer
look at it)
