Galactic Bounties 1 Event

I'm so upset with myself! I didn't realize I would only get 2 battles, regardless of whether or not I won the previous tier... I thought if I started on tier 1 and kept winning that I would be allowed to progress through them all. Nope! You get to choose 2 battles only... I have never seen this event before so God knows when I'll get another chance to use my Bounty Hunter squad ☹️
