About the Monster Book Glitch

I have a question...Say I get a new monster's card and log out and back on. Will the card be moved? I thought I heard there was something glitchy that happens when obtaining the new cards.

Also, does anyone know if Elin Forest monster drop their cards? I know they're in the book, but are they dropping?

New card as in what? Just a card you didn't have? If it's that, then nothing will happen. If you mean a card from Time Temple or Ellin Forest (yes they drop cards, and yes they also cause the shuffle) then the next time you log out your book from that monster card forward will be shuffled. Based on how many card you have, this may or may not be noticeable immediately.
