I finished the Trail of Ithaqua quest today, and the game announced that I had unlocked an investigator (Wendy Adams). I then went to start a new game with Wendy (so I could see her stats) and she was still marked as locked. I went through and played the quest again and got the same unlock message again, but still she was not unlocked. Anybody else have this problem?
(Additional information that might be helpful: I'm running Elder Sign: Omens on an iPhone 4S, iOS 5.1.1, and I played through the quest both times with just Rita Young in the party.)
