I just bought, for what I thought was the first time, Little Reds Hideaway Map. I unlocked the challenger, but I had already done that once before (and battled it). Should the "unlock challenger" option even be there if you've already redeemed it? Am I now out 250 CSC because of this?

File a ticket, you can get your csc back probably

They need to change it so the unlock option goes away once it's unlocked. It's been like that for forever though :x

Thanks. I thought I was going crazy when I saw the challenger already defeated.

Yeah, I had that happen a few months ago. It shouldn't be an option or at least not an option that tries to work and steal your CSC. I didn't file a ticket or anything, but I'm still annoyed about it. :P

It really shouldn't be an option, but what can you do?

I filed a ticket and got the CSC back so I'm good now.
