However, in the unlikely case where the player gains another the new star via daily 4% skill boost, the system may miss this gained star status and effect. This has happened to me once. Maybe this is a bug when the system does not trace quality increase and follow-up effect with that daily 4% bonus option.
Should report via in-game support to ask them to add it back for you. Hopefully it could be resolved before your important match starts.
