It appears the the recipe unlock event is has now reset, current percent is <10%. I don't think this is intended.
The team is aware of a bug related to this event and we are actively working on resolving it. The resetting of this unlock is not intended behavior, as such please stop donations while the issue is under investigation.
FYI this has been resolved

Hype is the path to the dark side. Hype leads to unfulfilled expectations. Disappointment leads to anger. Anger leads to disgust. Disgust leads to "oh, new shinies! I'm back!"
