Well shit.

If you want them, you'll have to take it back to EB. And then wait, and probably not get a replacement.

On the bright side , you might not actually miss some of that stuff. The poster isn't really a poster, more just a bit of card with a picture on it. The stickers, well, they're stickers, and I am choosing paint in their place. The instructions would be nice though.

So let me guess, this didn't come in an outer box - you received it in just the slipcase, right? Cos otherwise I can't see how those parts came loose.
