Yeah, it's the usual end-of-event calm I guess.

I did manage to clear the stage 1 whaleship missions, which was a surprise and actually I'm doing something I was not planning - farming these missions to get the shop jewelery.
I've burned through quite a few (100+) stamina pots already and bought all the 32k and 25k medal jewelery.
I think I'll finish on the 23k ones this time.
The additional manyuus and ampies (got 150+ of each already) that we get from those missions are actually good for the current synthesis event and incoming 6*s.

EDIT:
The app was announced to be released at the "end of August".
