Maybe this is what happened to Moon+reader on your device. To prevent this from happening set Moon+Reader for auto update.
I still haven't got the new Play store, and I'm not a fan of auto updates, but if it happens again, I might try it to see if that would solve the problem. I usually have a reader on, so I don't like auto updating apps..
