Bug fixes in World Championship DLC

Automatic class change: Fixed an issue where footballers with multiple learned classes in the player's squad could reset to their initial class.

Bypassing formation restrictions: Fixed an exploit in the "Restricted Formations" mode that allowed changing the tactical setup during a match by changing a footballer's class.

Game crash when no footballers remain in the club: Fixed a crash that occurred when trying to access the club screen if no footballers remained in the squad during the final stage of a national tournament.

Post-match game crash: Fixed a crash occurring after a match under certain very rare circumstances.
