On my list of things to look at.
i've heard of this happening - but not got details so been unable to track it down so far, even knowing the leagues etc. involved would help as its definitely not common.
If you can get me a save game with this in then it would be hugely helpful.
This will be fixed in a forthcoming update.
This hasn't changed to my knowledge - any chance of you sending in your save with a note to check (it might me your kids just haven't got the potential you think they have? ... or need to mature some more before improving further).
I think that's a tad harsh myself, but obviously you're entitled to your opinion.
(I've personally played through two complete 30 season games without coming across any of these issues tbh and our review scores in the stores aren't awful, so I presume not everyone is hating things as much as you seem to be)
PS - We're somewhat busy and so can't always respond instantly to threads, please be patient when you ask for feedback (I'm actually on holiday today believe it or not, about to jump on a flight to watch my eldest daughter in a play).
