Indeed, the previous event gave one ticket from the challenge stage, and one from the treasure rally phase 2.
I've been looking to getting the same this time but no, they chose otherwise.
finished da event long time ago
after getting all amphies,
trying to get all purple manyus for Leu
I don't think it was "chose otherwise". They gave us that event out of order, remember? My own guess is that at some point they updated their events to do a ticket on it, but our "normal" event routine hasn't gotten us to that point yet. It just looks odd to us because we're not always getting events in order.
The last one was also a special holiday event, this one was not.
rolled few five stars from gacha... so, basically, 6 stars = ssr, 5 = sr, 4 = r ?
