Help!
I got blood for the matron mother in the underdark, and AFTEER I gave it to her, I talked to her daughter, and accepted the fake eggs.
I also accepted the fake eggs from the guy who was her former lover.
Now, when I try to switch them, the whole city turns hostile!!!

I've tried sanctuary, improved invisibility, nothing works.

Gamebanshee suggests you get the quest from the mother, get fake eggs 1 and 2, then switch the eggs BEFORE giving the blood to the matron mother.

Do I have to run Ust natha again!!!
am I screwed?

Any help would be appreciated.

Only think i can think of is that maybe you're missing a time limit?
