I waiting to see if they fixed it or only made 10 pulls count. Because I've been saving scrolls and if they made only 10 pulls count alot of people are going to be mad! I'm hoping it's just bugged because a guild mate had the same problem last night
I just did a single pull, and it worked fine - I think your guild mate pulled too early.
My bigger complaint is that pulling 100 times takes bloody foreverrrrrrrrrrrrrrrrrrrrrrrrr I wish there was a way to bundle those single pulls into a 10x - even a 11-1 ratio would be reasonable.
When I first saw the event open, it said "7days 3hrs... left", and it didn't work.
So I waited 3+ hrs until it said "6days... left". I think these events only last 7 days, but the announcement thing opens a few hrs ahead of time? Probably cuz the nene/anemone event ended ahead of the usual transition time.
