Absolute Ring Event

It required 31 days before, you could get miss two days on a ring, or a day each on two rings and still be okay. They just reduced the required days by one, so it's 30 now, which is one extra day you can miss.

Have you gotten a 12th stamp before? I was unable to do the 12th day on any of my characters, Gaga only told me I already had 11 days done despite my ring being in storage, so I could neither get a new ring nor upgrade it.

yea, i was able to do the 12th day, but only on the character that had missed a day (like the 5th or something), on shinku who had done day 1-11 perfectly, it didn't allow it.
