http://www.buzzerbeater.com/BBWeb/Forum/read.aspx?thread=... I did post my first complaint on the help forum. At the moment, most of my players got stamina upgrade, with arrows up. That is the solid reason why I'm 100% sure i got stamina training (like i also said, system log should have the same information, please check it to confirm instead of shaking the users.)
Later on, all arrows up disappeared after my post ( I see it with my both eyes), then only one player got handling up. I got some other players who played for 88 minutes on the training position, and received nothing.
Unless you are saying players who play less get training and those who play more get nothing. Then this is not a bug, but frustration from user point of view.
