6864: a simple packaging error?

It's Samuel, a young and loyal reader of this blog, who points out to me this once again disturbing and disappointing detail: The box and all the official visuals of the set 6864 Batmobile and the Two-Face Chase presented Two-Face and his two henchmen with a colored hand Light Flesh and the other Dark Bluish Gray.

Everyone who has received the set so far has obtained minifigs with two hands in Light Flesh.

This type of error, no matter how small, should not happen. The consequences are minimal for consumers, but again this error will fuel a hypothetical speculation on the exit of the set with the hands in. Flesh et Dark Bluish Gray as presented on the box.
