The Fiona Sidequest

[Flamethrower]

I'm trying to complete the Fiona/Sunken Desert sidequest in CT, but I'm having some problems. The walkthroughs I've read say to go to Fiona's Ville and talk to her husband, but when I enter it, her husband isn't there, only Fiona, and there is no sunken desert behind her house like there's suppose to be. Is there something I have to do before I can do this sidequest?

If I recall correctly, it only shows up if you have that woman back in Zeal plant the sapling rather than burn it. Could be why it isn't showing up for you.

Thanks Super Christ!
