Help! Need work around for show-stopping bug.

[Alastair]

Hello,  I've been playing happily with many mods installed all the way to the underdark without encountering any severe bugs.  However, I have now run across a dreadful glitch that threatens to end my game.   

After collecting the bits and bobs that the Matron Mother needs to perform the summoning ritual there seems to be no avenue I can pursue that does not turn the ENTIRE of Ust Natha, including the matron mother and her daughter hostile.  If I accept Pheare's (sp?) offer then pinching the eggs turns the city against me, and if I refuse, attacking her turns the city against me.

What should I do? Is there an item code to create the real dragon eggs in my inventory so i can give these to Pheare without having to actually nick them from the temple perhaps?  Is there some way to open the gates of the city myself?  Has anyone got any other bright ideas?

I would be ever so grateful for any help, I was really enjoying myself up to this point.

Thanks in advance!

   - THE DRAGON'S EGGS

      Phaere details her plans to overthrow the Matron Ardulace and set herself
      up as head of the house.  She wants your help in this, so agree to help
      her get rid of the Matron.  House Despana is going to use the Blood you
      collected along with the Silver Dragon's Eggs to summon a demon.  What
      Phaere wants to do is replace the Eggs with false ones so that Ardulace
      is destroyed when the demon is summoned.  She can then use the real eggs
      to gain control of the demon.  She gives you a key and a set of false
      eggs marked as "Phaere's".  Leave her house.

      Return to the Temple as that is where the eggs are kept.  If you did well
      by Solaufein, he will appear near the entrance with a further proposition
      for you.  He wants to give you a second set of false eggs that you can
      give to Phaere.  This way both the Matron and Phaere get killed by the
      Demon.  Agree to his plan and enter the temple.

      Brian Camley has an interesting strategy for the temple:

        While I was in Ust Natha, and was sent to retrieve and replace the
        dragon's eggs, I really didn't feel like fighting Drow and Golems, so I
        saw if SpookyScarecrow's trick for the Golems in the De'Arnise Hold
        would work in this case - I gave Aerie the Boots of Speed, and had her
        cast Sanctuary.  She got in and out quickly - this works for most
        encounters with guards of some sort - the exception being, of course,
        getting the Gesen Bow String - using this strategy will leave your
        cleric trapped in a room with some angry guardians.  Not a good idea.

      Once in the temple, take the passage immediately to your right, and take
      that up to the Egg Room (x 2067 y 780).  Kill the 2 guards and enter.
      There are 5 Golems in here, just waiting to pounce on you once you have
      taken the eggs.  Kill the Golems.  Take the Real Eggs and REPLACE THEM
      with PHAERE'S EGGS. (don't forget to do that!)

      Back to Phaere's.  Give her Solaufein's Eggs (20,000 experience) and she
      seems awfully pleased.  Well, that won't last.  Listen to the Imp when
      it appears, then get back to the Temple.  Phaere is right within the
      first passage and soon the Ritual of Summoning begins.  The Demon kills
      the two Drow women one by one, then will leave if you remain silent.
