You got lucky! It’s a recurring bug that has something to do with caching. It’s actually happened quite often, and it’s devastating for the concerned item when it does.
Due to the repetition of the issue, it looks like it’s something that cannot be fixed for good and will be repeated again at some point. So once again, I ask Envato to come up with a way to compensate items that have suffered from this issue. Offering new exposition time for those affected items would only be fair!
