Regular playing bug?

Hey guys...To put it short, this game is stupid. And this keeps happening every year, SI guys still didn't fix it. I'm in my second season with Sporting CP. Gelson Martins was a rotation player due to Andre Carillo, and since Carillo was leaving on free transfer to Bayern, he was going to become a starter. At the end of the season, the very end, Gelson approached me and wanted a chance in the first team. I sad he'll get his chance, but the season was over, so naturally, next season he was going to be a starter. He went to Euro 2016 with Portugal, then after that to Olympics (against my wishes, but I couldn't withdraw him, another idiotic "feature", lost 5 players due to that stupid tournament), he came back, and of course , he was fatigued. Gave him a little bit of rest, then he played 7 games in a row, 5 of those till the end. He approached me now, said he had enough of me breaking promises, and he wants to leave. Wtf? He couldn't play when he was away on international duty, but the game didn't register that, and when he could, he did. Similar thing happened when players who played regularly also moaned how they aren't playing when in fact, they are.

Does someone have similar experiences?
