Xaryu, there is a work around it just takes a little time. What you can do is put all the items you want to copy onto a mule, save the mule and then make a copy of the characters save folder. Then go back in game and transfer all of the items back to the group stash (has to be group not the characters), exit to main menu, erase the characters save folder and put the copy in its place (be sure to paste the copy not just move it or this will only work once). When you reload character they will have the same inventory again and you can move it to the group stash again. Rinse wash repeat; for a faster time once you have transferred 3 or 4 times put it all back on the character and make a new copy of their save, its a way to quickly increases the amount of items you are transferring. Its a little more work but you can quickly transfer large amounts of components that way. Know its not perfect but this is what I've done in the past to increase my components quickly.
