When updating to 1.00.39, you may have had your data reset after being brought back into a tutorial in a previous shop.
This bug is an unintentional byproduct of some tutorials getting skipped, so players are forced back into the tutorial with the exact data expected of that tutorial.
We put in a fix in the next coming version (1.00.40) so that this kind of rollback does not ever happen again. Unfortunately the rollback is irreversible as we don't have access to manipulate the save data for players from our end.
We are working on a way to compensate players affected by this through redeemable rewards instead. We'll work that feature into a later update. In the meantime we'll keep track of those who've reported that they've been affected by this.
Our sincere apologies to everyone. We've had a rocky (buggy) launch but we'll make it right. We hope you give us another chance! 🙇
