Hello Team
first things first: english isnt my primar language, so im sorry for some missspeeling etc.
Now for the Problem: yesterday i hit once again 9000 Kobans, so i gave Gacha Shot. Sadly only some booster but with those i was able to hit Stage 8000+ and unlock a new girl.
When i today startet the game again, not only was my Kobans all used (which is fine, cause i spend them) but my Stage progress ergo the unlocked girls/boni are all gone too. Funny enough, but the Progress i made in the Event was saved, but not the one in the normal Stage.
Here now my Question: how did this happen, and can it be undone?
