All the problems that are being described started about 6 MONTHS ago for both my teams. So if it does have anything to do with the last updates I'd be surprised.
On and off over the last week my first team has been able to get 25 or more boosters throughout the day. Ok, about half of these have to be taken as condition boosts to directly improve a players condition (i.e. I can't save them.) This happened after a did "something" with my Facebook account. Don't ask me what. Something to do with privacy settings, I think.
My 2nd team, played on Android only, is getting sweet FA despite having reset my Google ID (or whatever it is).
TBH I'm past caring anymore.
Going to have next season on wind down. Followed by at least 2 seasons on holiday.
Once the rugrats have gone back to school, the World Cup, Tour de France and the Vuelta have finished I'll see if I can be arsed.
