- Golden apples have a very small chance to appear any time you pick apples in the park. The two spots come back every time you sleep. (Or if you're into save scumming, just save on the screen with the apple spots. Which type and how many apples gets determined as soon as you step on the square.)
- Cassie needs to be saved before you can bring people into the safehouse. To start the quest line, you actually need to go to the slums and bully the guy who demands 5 credits to let you pass. There's a whole lot to the quest, and there are many possible ways to get a bad ending while doing it. Don't feel bad if you need to look at the wiki.
- Rinny needs you to understand the dangers of magic before she will teach you. Someone in the tower library can tell you.
