So I complete tier 3 2x. Farmed the rest of the tickets to do the 3rd time of tier 3. I got the message above . I had 280 of the 330 shards needed to unlock her. I had to go thru the unlocked Rey to get to tier 3 . I’m posting another pic of how I got around the not meeting the prerequisite message
