The vending machines what you get from your class quest is really stupid once you put them down you can not pick them them up again and can not get any more so if you in a temp place and want to move say across the map you are totally screwed why you not made it so you can pick them up again ...really bad idea the way its done.
And diamonds are useless all you can make is a diamond pickaxe and fire axe why you not made diamond armour because diamonds is so easy to get now in this version........please add something else for use with diamonds have over 200 useless ones now
