Oh, I agree there! They should REALLY fix that 1-hour race-reward window.
Nutaku (I know you keep an eye on these forums!), in case you wonder: You have customers who have jobs. Not everybody is able to play this game at their job, but they're nonetheless jobs that earn your customers money, allowing them to invest in Nutaku games.
Same can be said for people sleeping during that 1-hour window (Aussies, Kiwis, Asians, people on NIGHT SHIFTS) to obtain and use those swan-race rewards. People need sleep to function at their job. And I just explained how YOU benefit from your customers having jobs. Don't risk your customers' jobs by having them wake up in the middle of the night to collect those rewards!
The solution? It's pretty simple: keep the exchange or gacha or whatever that's related to swan-race events open for a few more days. That is something you already did for other events, which actually didn't even need that extra time because they don't suffer these 1-hour windows to obtain and spend rewards. But the one event that actually needs that extra exchange time never got that fix! And I suggest you prioritize fixing this before phase 2 starts, so, now you have 1 hole day to accomplish this.
