MyVoiceHurts: Hello,

So, I've spent a huge amount of time banging my head against the wall on this to the point where I looked up on forums what could be going on. I'm trying to complete the Lock and Key quest, which I understand requires that I trigger Vaska suggesting I give the psilocybe to the Hierophant by a) saving the lost child and b) saving all three camps of brickmakers. I did that, but she won't talk about the Hierophant, and when I talk to the Hierophant--even though I have the psilocybe--he won't trigger the quest. Have I bugged the game somehow? I understand I need to do this to progress. Any help is appreciated. Thanks.

I tried to attach my save file, but Galaxy wouldn't stop "processing" it for over five minutes. Can email if needed.

Caesar.: What is your current phase in "Lock and Key"? The pscylobe affair is actually a secondary quest, called "Diplomacy and Hunting". Do you have it on your journal? According to the wiki, it is possible to skip this quest if you manage to complete the last part on your own, just by walking into it so to speak. And to make things even more complicated, there is a third quest that you will need to complete to advance ("Following the Thread").

If you don't fear spoilers, the rest is here:
Lock and Key
Diplomacy and Hunting

(If you don't want to spoil yourself, at least check your current phase in Lock and Key and whether or not you have DIplomacy and Hunting activated).
