wont let me craft certain items

i got the new update and wanted all the new cool things you were working on, so i made a new world and it was great! loved all the new stuff was really cool but then i tried to create a wooden fence and it wouldnt let me, i thoought maybe its just a bug with the world so i deleted it made a new one and same problem i even found fence destroyed it placed it and still nothing, the new doors that can be made works fine just i cannot craft fenceing which is a bummer. there could be other things i cant make but im such a novice i dont know all the cool things i can make. i mostly play for fun anyways and it doesnt affect my gameplay much so just thought id let you know. ps. great game keep it up.
