Summarize your bug Prestigious Quest: Bounty Hunter (3/7). I didn't get any score for victory in the third requirement: "Win 12 Battles with IG-88 in Territory Battles". I won a fight (4/4 in current Geo TB) and still have 0/12 there. My team was: Bossk (lead), IG-88, Boba Fett, Jango Fett, Dengar.
Steps: How can we find the bug ourselves? 1) Enter Territory Battles 2) Enter a fight with a team consisting of IG-88 3) Win all the stages in the battle (4/4) 4) Click on Quest -> Prestigious Quest: Bounty Hunter (3/7) 5) See that the victory didn't count.

Since my guild is quite advanced (average GP ~3kk), we don't to TB Hoth anymore. The only way to finish this quest was to complete 12 P1-battles with Bounty Hunters squad (the difficulty level in further phases is ridiculous). I won a fight (see screenshots) and it should state 1/12. Unfortunately, it still states 0/12 despite winning a battle with IG-88. My entire team survived the battle, no character died during the fight (if it helps).
