Hi.
I got this problem too (today). I played Gacha and received the Deluxe Appointment + the Leather Mask.
The first one has been activated instantly and the Leather Mask appeared in the Shop Section as : Kinkpoints 0 and buy 0.
After a refresh it simply vanished and I did not have the 3K Kinkpoints.
9K of Ryos for nearly nothing ?
Thanks to the support team for having a look at that and fixing it.
Keep me posted.
Best regards.
