Still no Stamina/Energy while playing World Cup in Managermode

In Manager Mode during the World Cup, stamina regeneration fully stops after the season ends on June 30th.

From that moment on, my World Cup players never recover stamina anymore, making every remaining match basically unplayable.

No issues before June 30th, no issues with club players. Only the World Cup squad is completely bugged.

Hard to believe this happens in a 69,99€ game.
