I was informed by a clever wolf that iPhones don’t allow the game to close its own notifications.
An implication will be that the +X other events counter will double each time, if you don’t close them manually.
Or rather increase with (X + 1) * 2 - 1, where X is the previous count.
I intend to hotfix this issue today.
Thanks @Shinyuu for the report!
(Fixed in patch release v1.59.2)
