I've put in some things which should help speed up certian. I've disabled "sell entire deck" because I need to re-code it (I doubt it'll be missed) and I made Moving entire deck quicker.
I sitll haven't figured out why some decks are appearing empty (Make sure that hwen you make a deck, you START FROM THE BEGINNING every time you re-try, because it it fails it deletes the deck it created in the first step. Also make sure it did successfully make the deck on that page)
I think it's a side effect of the lag which should be lessened at this point. I hope so.
