I can't progress out of the Temple. It says that it is not yet in the game. I also can't talk to Cassie. Wouldn't that be the the way to the Desert? I skipped some versions when I downloaded the most recent one so that might be the cause.
Make sure you've done everything you can in the temple first. There'll be a point where you can leave again.
For Cassie, you need to do her route. To start it, visit the slums and force pass the toll guy, then sleep and return to the slums!
