When Following the CoreDataBooks sample code and implementing it into my app, I have reached a very odd bug/glitch with an NSNumber(Integer 16).

When I have the code

```
cell.detailTextLabel.text = [NSString stringWithFormat:@"%i", child.marblesneeded];

```

the detailTextLabel displays an odd string of numbers that changes every time I try to change the numbers. See Attached Image. Currently, it should display 0 but it displays 112917120.![enter image description here](https://i.stack.imgur.com/DYtsg.png)
