"Knights Code of Chivalry 4:Persevere to the end in any enterprise begun.
A true Dragon Knight shall never give up, no matter the obstacles faced.
During the event, only those who log in every day from the beginning to the end will receive 10 Dragon Knight fragments as a final reward for their perseverance."
It's said that you'll get the 10 fragments on the LAST day of the event. The 0 frags glitch was just a mistake, nothing more. But players weren't promised frags today anyway, so don't worry, you'll get the fragments if you are dedicated enough to become a true Dragon Knight!
