That's weird. I was getting experience just fine from explore rolls. Given the history of the way bugs have been handled before, I doubt we're going to see anything done to fix the keys. Pero Pero's developers in Japan are too sadistic for that.

Oh, I guess I need to send a support ticket, then.

Ehh and i bought ~120 N gacha and 1 E gacha... doubdt they will retroactively fix it now :/
