Reading this thread made me give in to the urge for “just one more pull!” - heh heh.
It was weird. I clicked the portal, spent the gems, and… it just sat there. About 15 seconds went by, and then I saw the little “wifi icon” that indicates my connection to the game was poor, so now I’m worrying that it spent the gems but wasn’t going to complete the pull.
5 more seconds, and then… Guardian Falcon!
OK, so NOW I’m done… that’s plenty of luck for this week: 3 pulls gets me Jackal #3 and my only Falcon.
