So PAVI259 just created a new Iron Farm for us on Smp3 at our Frontier settlement. It works fine except that every time someone logs out from our base when 2 or more people are there, all the signs on the left side of the horizontal water tube, detach themselves, burn in the lava and then the lava flows out creating cobble, smooth stone and blocking up the Iron Golems, backing up the system. We fixed it 4 times now, change the distance of the tube, added more signs. And yet the signs on the left keep falling off, burning and breaking the iron farm. I know log ins and log outs probably have nothing to do with it, but I wanted to include all the information. Thanks!
