Knowing that this is affecting a majority of people is enough to keep me at ease, all I can do is wait for a solution.
Only 8 days left for the event ends, they gonna have to do something in a week, but im betting they will solve this pretty fast.

They repplied me saying they're receiving lots of tickets with the same issue and they're trying to fix this problem asap. For who have questions, just send a ticket to them.
