I have a rather important question. I believe a similar one was already asked, but I can;t find an answer...

Do we lose unspent Moon/Sun scrolls every week? For example, I have 80k Moon scrolls, and I want to save tchem for the next week, does that mean I will lose 50% of these and start next week at 40k? I mean, do I have to spend all the scrolls or else I will lose half of it? Would REALLY appreciate clarification on that one.
