I haven't been very active with collection of free SS nor reading in the last 2 weeks, however I did collect free stones multiple times (at random times) but the amount I have is hardly kept near 700 mark. Last time I collected stones, 2 or 3 days ago, I have somehow reached 723rd stone, yet, today when I logged in I had 673 stones (further spent another 20 so now I have 653 of them). None of stories in my library have auto unlock selected and none of stories had change in chapter from where they were left. This happened multiple times already (I had a long time struggle to reach 300 stones from 200, reaching 500 from 400, it didn't matter whether I was reading premium or not, the stones simply wouldn't accumulate as they kept disappearing. Those examples happened months before this rework on earning SS.)
Any idea why stones have vanished and hopefully a way to prevent it)
