But it's really annoying, if it happens with Kurito :X
Got an answer by nutaku because of theat problem:
Hello,
We are very sorry about the card retrieval issue that appears to be affecting many users in the Gacha and Kuritos nest. We are currently investigating what caused the problem, but rest assured, you will all receive the cards you are missing soon! Sorry for the inconvenience!
Thank you for you supporting Nutaku!
