So I was battling a Gym and literally was down to the Coup de Grace on the last Pokemon, when a Raid was announced for that Gym. After I killed the last Pokemon, I was displayed the congratulations message, but the Gym never turned White. I opened the Gym backup and instead seeing the add your Pokemon icon, I saw the icon for my Pokemon storage. I selected that and was able to browse, select and leave a Pokemon. But the color of the Gym never changed. I should have taken a screen capture, but didn't.
Has anyone else seen this?
