wow this maybe the 1st time bug issue that i report on forum got fixed in quick time (less than a day)
eventho this is an old thread that i just necroed because same bug&issue happens/re-appear again.
but back then in march 2022 the bug never got fixed and i have to re-train another player to 6*. maybe because he gain star after match finish hence they didnt recognize it unlike gain star during training..
