If you have OCD and/or like to keep your inventory organized, here's something I just noticed that may have been reported already.
ALCHEMY WILL TAKE THE FIRST ITEM YOU HAVE IN YOUR INVENTORY IF YOU HAVE MULTIPLES OF THE SAME ITEM.
With this Starter Kit, it said I needed an Ocean Top, which I had two of. It took the one I wanted to keep and not the one at the bottom of my inventory that I got from Daily Chance.
It is strongly advised, then, to put extra items you intend to use for Alchemy at the TOP of your inventory if you have multiples.
