I´ve got a really stupid question...but I seem not to be able to answer it to my self. How can I create/Craft stairs? I see them in Videos or read about them in the forums (how to move/turn them etc.) which means that they do exist and can be crafted already. But how exactly do I do this? I´ve got installed all necessary workbenches already, but havent found the respective class that holds stairs to craft. Can someone please tell me which workbench I need for this or what I´ve got to do?
