Greetings FS City,
We have found that if you purchase a character DLC while using temporary character ticket, you won’t be able to see the character unlocked when the ticket is expired. For example, when a ticket to try out P5 Rebecca is in use, you are not recommended to purchase Rebecca’s DLC as the system wouldn’t recognize your purchase and the character would still be unlocked afterwards.
We encourage you to contact CS when encountering this issue at https://3on3freestyle.zendesk.com/hc/en-us/requests/new
We will have this fixed as soon as possible.
Thank you for your patience and understanding.
