With Ganso or David Silva (great passers) in the team, when the player passes a lot in the game, more than 100 attempts for example, the number changes to negative, like -120 and sometimes it disappear, so no more 130(100) stats...
Don't panic mate - all fixes which happen on Android automatically go into iOS and vice versa - they share the same codebase.
(although the next iOS update will be after the next Android one, don't panic its not that I'm neglecting iOS - its just that the vast majority of fixes are Android specific items - ie. installer tweaks etc. and iOS is incredibly stable/sane in general at the moment - next iOS update is 'planned' for the end of May all being well, as a 'wrap up' update to catch all remaining issues ..)
PS - If you post something and I miss it, feel free to kick me ... I'm kinda busy so will miss things from time to time.
