4 teams lost in today TW due to crashes.
3 in previous TW.
3 Haat solos lost due to crash in P4.
Several fleet arena battles lost due to crashes.
Some casual crashes in home screen or while watching inventory....
iOS 12.1.4 (updated), iPhone 6.
I just posted this on Answers HQ, and many other players had the same problems.
All with iPhone 4-6s.
They are investigating it seems... but this was clearly a consequence of last update ad should be fixed as soon as possible.....
Edit: I checked again Answers HQ, and also other phones are affected.
