I did the free 10 pull on Alina and it had 9 blues + 1 purple, then when I clicked to start going through them it didn't let me, and instead an animation played with a clock rewinding to before the pull and had Namae doing the whole thing again which resulted in this one
I know sometimes it does a "surprise, your blue was actually a gold!" fake-out but I hadn't seen that before, is it a new thing with one of the recent updates?
