Hi, i've created a new furnace in my forge mod and its simply a copy of the normal furnace, except it is a multiblock. so the problem is: when my new furnace block is placed in the world both client and server create a tileEntity for that block and place them at the specific location. now when opening the gui the progress bars refer to one tileEntity which isn't updating while the burning process itself is done by an correctly working tileEntity. why are there 2 of them in one block?
