I've seen "New Game data" appear and kick me out of the game more times in the last 3 days than I have in the previous 2 weeks (and that includes around the bugs in 4.9.1).
Is this actually new data, or do we have another bug where the game "thinks" there is new data and then forces a restart?
PS: Each time, my battle speed multiplier is reset to 1x, which is just another annoyance on top of the restart.
