I just accidentally updated JPdori from the JP Google Play instead of QooApp and when I opened it, it said it was downloading 1 GB of data. I had a very long minor panic attack right there because I thought it was overwriting my data, but it was actually just redownloading all the data that I already had, so I'm extremely glad about that. I legitimately thought I was about to lose my dream cards.

Edit: Why did I talk like that? I guess I'm still in panic attack mode and it completely changed the way I normally talk.

Edit: Oh okay. I just looked at the BanG Dream! twitter and it said that was happening to people, so it's not because I updated it from Google Play.
