We have confirmed that there has been a display issue for the Special One-Time Bargain Set. The Special One-Time Bargain Set description in-game indicated players would receive Monster Points upon purchasing the set. However, the Special One-Time Bargain Set gives players Pal Points, as published in our official announcement.
This issue has been resolved as of 12/13 (Thu), 6:02 PM (PST).
For more information on the Special One-Time Bargain Set, see here.
Details on the compensation will be announced at a later date.
We sincerely apologize for any confusion this may have caused and thank you for enjoying Puzzle & Dragons.
