- Heya;
2011 was a special year in terms of re-releases, because it is the so far only year during which we had two of them! :)
Long story short, what happened is that the re-release box on the 18th wasn't adopted even just half as often as Nick had anticipated.
Because of that, the number of high-value pets that were re-released was lower than it was supposed to be (since the probabilities weren't meant for such a low adoption rate).
To make up for this, we got a second re-release on the 24th.
Hope that explains it!^^
