Hi,
The update 1.12 went to HIB on Thursday. After delivering, we do not have influence on it and we can just wait until it goes live (did it, by the way?)
Regarding 1.13: "1.13 - Fixed loosing progress after update, cache problems and looped downloader. -> Update not required in Humble Bundle!"
Please notice we're really trying to solve issues. If I'm not sure the update is free of bugs then I can't say it'll go on, say, Monday. I did once and encountered delay becuase of bugs and then some forum users were "not-too-friendly" becuase of it. It's not helping either.
Please, let's respect each other, it really makes things go better and faster.
Peace
