Thank you for playing DISSIDIA FINAL FANTASY NT.
The following issue has been addressed with the patch implemented on Jul. 5, 2018.
During custom matches, initiating battles with a team of only 2 players and no COMs would cause an error on the Briefing Screen.
We sincerely apologize for the inconvenience this has caused.
We hope you continue to enjoy DISSIDIA FINAL FANTASY NT.
