Hello,
It has happened on a number of occasions that sometimes the X's will disappear from the deduction board between sessions. It is not even the most recently clicked boxes either, it seems unpredictable which ones will be affected. It does not occur often, but when it does, it can really mess up a game if it is not noticed right away. Other players have commented that they have experienced the same thing.
Do we know why this occurs? And is there a way to fix it?
Thank you
