Hello! It has come to my attention while browsing the factions shop that some items are missing and some that cant be sold by /sell hand. My first suggestion is adding Pistons and Sticky Pistons to the redstone area of the shop. As for selling, ive noticed you can buy cow spawners (Yes I know it was probably intended to be bought for food) but you cant sell beef or cooked beef. Cow spawners could be used as a nice little source of income while working around your base (if you have the correct farm set up).
Just a suggestion though.
