We are many to meet the problem in our team :
In fact you're unable to power on your amaments (i mean you choose A/G but in fact nothing happens in the HUD) or unable to see the ccrp fall line or ....
At first we suspected forgetting something in the procedure but after a while we realized that as soon as this bug appears and we return to the base (RTB)... when the wheels touch the ground the plane go trough the Tarmac and seems to sink in a mixture of water and track (with a sound bug too).
And after that, you're unable to pick up another plane because of as soon as you pop in your cockpit, the same think happens.
If you want to play again without problem (bug) you have to exit the mission and reload it again.
