I just purchased niko from the vendor and when i go to unlock him it says i need to complete his mission but i have no alerts for comps and i can't click anything on zakkul to start his mission

an issue i have noticed is that the sith warrior juggernauts normal saber hold when our weapon is drawn is no longer single handed grip to our right side but was switched to the the jedi knights two handed grip to our sides during the spirit of vengeance fps
