Lucid Nightmare Bug

So, in the midst of doing the Lucid Nightmare run-around-everywhere thing, when I reached the part in Gnomeregon where you have to have to change the Numerical Consoles, I found that no amount of clicking on them would bring up the window that would allow me to change the consoles. I get a little speech bubble pointer when I hover over them, but nothing happens. I can click the silver plate and get the clue, but otherwise, I’m stuck.

I’ve uninstalled my add ons and refreshed the user interface twice with no effect.
