Did 4 pulls, didn’t get LOCK, Kasumi, Eve or Tomoe but I got 2 four stars and the Moca I really wanted!!

If you’re wondering why I’m not going in all caps like usual, it’s because I’m really scared. I feel like Project SEKAI destroyed my iPad. I couldn’t do anything on the and it was making BanG Dream lag more than it ever has, so I deleted it sadly even though I had an awesome Rin four star and almost enough crystal things to do another pull for Len . . . But then when I went back to BanG Dream to do my 4th pull it crashed the app, which it’s never ever done before except for one time when my storage was completely full, and I couldn’t even see what I had gotten on the gacha. Is this happening to anyone else? I’m freaking out. I don’t want my iPad to be completely buggy because of that dumb game (some apps won’t even open for like ten seconds when I click on them.)
