I don't kown the usefulness of "lever" can you be explicit ? Bug : - our caractere is always top of "chair" but we see the other player has the right height. Suggestion : replace in config the NAME of block by Name OR ID_item Otherwise very good work that has strongly can sit on any object (especially the step). Other suggestion: Add "press_key" for seat anywhere. (eg "u" character for the seat) PS :For me it's work on my server in 1.2.5 !
