Pack : Direwolf20 Pack Version : 1.3.1 Mod Version : 1.7.10-9.6.10 I've made a 5x5x5 tank with no problem in my world. I am trying to make a 7x7x7, which is allowable, and the tank doesn't assemble afterwards. I've got 2 valves set up, as was as some gauge on the front, and still nothing. My 5x5x5 is made with tank walls on all sides, minus the gauge on the front. Diameter according to the tool tip can be 3, 5, 7, or 9, and the height can be 4, 5, 6 , 7, or 8. So this tank should work, but for some reason doesn't. Any clues?
