Yes, fix it now, like how is this still in?
Leave it. I am happy know how it works to fix my spot, or not.
I actually want to avoid teams lowering qualities before season end.
BTW, I can imagine that some teams can also buy players to build team near the end of season. For example, teams which cannot promote to next level, and teams which keep in low quality like average 3 star so that they compete in 3 star league in every seasons.
