Aran can't CWKPQ: Official Proof

If it was because they are too lazy, they wouldn't have said if you are Cygnus or Aran, you may not enter.

It's a lot easier to code a simple check and this "you may not enter" message, than to actually go into the PQ code and make sure every reactor and room responds as they should to Cygnus and Aran.

I suppose it would have been even easier to do nothing at all, but maybe their testers tried that and saw that leads to serious glitches.
