Journey quest

Adding to this, I just completed: 

• 20 wins with full Empire
• gain stealth 100 times (thank you, conquest data disk whose description nobody read for letting me do that in one battle)
• unlock R2D2 

Which gave me some LSTs that allowed me to apply Krennic’s lead zeta (and scrap the rest for Kyrotech I really don’t need). The Journey Quest tab indeed disappeared upon completing the R2D2 quest.
