"Sees his footballing carrer away from the club"

Hi everyone. I was playing my game with Salzburg, had already won the title, and was preparing a cup final. I was going to play Rapid Wien for the league and after Rapid Wien again for the Cup. So I thought, "since I already have the league, might as well use the subs in the league game and save my best players to play the cup final". And so I did (lost 2-4 in the league game).

Suddenly, I had my inbox full of messages from my best players (my starting eleven and some subs i usually play) requesting transfer because they (and i quote) "See his footballing career away from the club".

Is this a bug? Because they have played like 30 matches for the club, they should have the intelligence to realize "Oh wait, we're not going to play now, not because he doesn't like us (since we played like 30-ish games), but because there's a cup final in less than a week"..

(P.S: Played them in the cup final and won 1-0 )
