Think of this. A few people dose the daily deal to get 3 Hearts and got a ton of them. They speak of that bug all over Discord and forums, a lot of other guys will jump on this bug and on the daily deal, Nutaku get more money than expected. After that, they only need to make daily deal with bronze/silver 2nd affection gifts and make even more money with theses bugs.
But not. They fixed it instead of take the opportunity.

But think about this: 3 Hearts for 100 NG was a pretty decent deal; a lot of people probably jumped on this one regardless of there being a bug. So, let's simplify things since none of us has hard sales data and say that 50% of people who regularly spend money on the game bought the deal before the bug was fixed. Once the bug became known, lets be generous and say that 25% of the people who usually -don't- spend money on the game then purchased the deal before it got fixed.

If Nutaku hadn't fixed the bug, yeah, they'd have made a decent bit from the people who usually don't buy; but they likely wouldn't be able to offer this deal again for a very, very long time; it was just way too many hearts to let go for only $1. Nutaku will end up making more money by fixing the bug and reselling the deal, and they know this perfectly well.

As for offering the 2nd tier gifts as a followup deal? Nutaku knows perfectly well that people would buy it whether there was a bug or not, but honestly I'd be surprised if they offered a deal for the gifts before there was a way to earn them in-game; sure people would buy it, but there'd rightly be a pretty big shitstorm about it too.
