It's strange. For the last few events we had, after the event deadline ended, yes you won't be able to buy those keys or cubes from shop, but the reedem option would still be there, just to avoid this exact situation where people missed the chance to reedem their points. Remember sailor sakura event last time, or the ninja plates?
I wonder why it isn't so this time. It doesn't hurt to atleast keep the reedem option there for one more day maybe.
That being said, I'd like to point out not to wait for last hour or preferably, last day to reedem these rewards. That deadline timer can be confusing at times. One good way to check event duraion is to look at 'time limited' section in shop during these events. On last day, they always shows exactly how many hours/mins left for the event.
As for the situation, I hope something can be done about your hard work (You got the bonus box every single day). But if I were you, wouldn't get my hopes high. Whats gone is gone. One way could be to have these points saved till next such events, but that might be very hard to do only at specific events and it wouldn't be fair either, since next time there could be better ninja/lower price and you will get an edge with these saved points.
