<t>Oy, I find him. I decided to go ahead and finish the post-game, but after that (and saving), it really irked me that I hadn't finished the subquests. So I went back to Forgotten Garden, and boom, there he was in plain sight. I guess I just needed to "trigger" him by stepping foot in the last area...

Yes it is post-game. There are 3 subquests after the main 20.

Help! I can't find the NPC who triggers subquest 22. I saw she's supposed to be in the Forgotten Garden, but I've searched everywhere to no avail!

I can't find the quest-giver for #8! I've walked around Port Soul a few times, exited and came back in, etc. I guess the only good thing is I distracted myself with Subquest 10 along the way.

Where do I find Great Horn Jerky for one of the Small Trays (subquest 20)? I've been all over the world, and even completed the "Meat Lover's Dream" subquest again in hopes the man would make me some -- but to no avail!
