Title: Ensure child and property exists.

Hello, I was having this issue:

```
c.child[c.i] = circularResolved[c.resolveTo];
^
TypeError: Cannot set property 'undefined' of undefined
```

I changed it so that it checks for them before trying to access them. It solves my issue but I'm not sure that's the real issue.
