Maybe my memory just bad but....

I bought yuumi like a few weeks ago and played her once. I then stopped playing for awhile and when I got back and wanted to play yuumi again, I found that it was not purchased. I was confused so I went to purchase history. Surprisingly I found luci was purchased which really awed me since i don’t like its play style so I doubt I would have purchased it nor do I have any memory of buying it. All I remember was going to store and getting yuumi. Weird... but who knows maybe I just have bad memory :D
