I think this part is the actual problem. The whole code is in http://pastebin.com/BL0ZhYMJ This plugin is made for 'instant' furnace smelting ant it requires this form of furnace: [C] = Cobblestone [SU] = chest to store ingredients [SD] = chest to store fuels [C][SU][C] [C][SD][C] ......[C] <-- and touching this will enable the furnace Please help me... Touching cobblestone shows nothing(only 'echo' at line 27 shows debug message the chest ids)
