v.93, Big Bang Update Notes

About hot time event, from spadow's blog, this happened in KMS

Because in KMS you only get ONE SP reset scroll per character. The SP reset scrolls will be given until July 21.
There is no second chance if you screwed up distributing your skill points.
Though, actually there is a second chance but you can only get it on one day.
An event ‘Hot Time’ will be held on the 10th of July.
To get another SP reset you must be logged on from 2:30 PM till 2:31 Korean time. This event comes with a bonus, you can win other prizes such as Timeless items and Cash Shop items.
Anyway I didn’t screw up my SP so there is no need for me to play during 2:30 PM.
After this event there will be no SP reset scrolls given to you.

Then theres's an entry on August 14th about event, I'm guessing it was done again for a 3rd chance of SP reset.

Once in a while there are pretty exciting MapleStory events. One of them is the Hot Time event. It’s an event where you have to be logged on before 2:30 PM.
When one minute has passed, you will get a package which has a SP reset scroll (100%) and a random item which can be a Timeless equipment or a cash item.
Today’s Hot Time event was different~ This time you can get a SP reset scroll and a mysterious love letter 100%! The mysterious love letter gives you a random amount of fame.
As a bonus, you can get either: a lucky medal, a cash item, useless potions, 60% scrolls, advanced equipment enhancement scroll or a secret mastery book.
