As of this svn revision (though I'm not sure when it began), a new bug appeared.
When you insert all of the planets into the chart, the room with portals to chapels opens.
Inside on the wall, there should be 9 unlit icons (3 per chapel) that are lit, as you trigger the switches
in the chapels. However, now all of the iconss are lit as soon as you enter that room (though switches aren't really switched,
cause Heresiarch doesn't appear.
I think they are lit as soon as I cross a certain line (that probably case of invalid initial value true/false).
