Hello. This is the Gravity Ragnarok Zero Operations Team.
We would like to inform you about the quantity of 
World Tour Tickets that can be obtained from the 
Cold Snowflake Box during the [3rd Anniversary Costume Party!] event period.
We have confirmed an issue where only 1 World Tour Ticket was being granted from the Cold Snowflake Box, when 5 should have been granted. This will be fixed and additional tickets will be distributed during the regular maintenance on Wednesday, December 23rd.
If you obtained only 1 World Tour Ticket from the Cold Snowflake Box before the fix, an additional 4 tickets will be distributed in bulk after the regular maintenance on Wednesday, December 23rd, so please keep this in mind.
We apologize for the inconvenience caused during your gameplay, and we will do our best to prevent similar issues from occurring in the future.
Thank you.
Gravity Ragnarok Zero Operations Team
