Other flight groups dosent take off?

[ataribaby]

Hi,
Yesterday i bought it on Steam and applied latest beta patch as i heard a lot of problems exists with released version. It works but later in RAF campaigns when whole squadron should takeoff only first flight of 3 aircrafts take off with me. Others sit endlessly on runway announcing takeoff via radio and leader endlesly circling over airfield probably waiting for whole group take off and form up. So i cant complete any missions with more than 3 aircrafts take off! Any help or proof it not just me?
