For some reason doesn't show up in JEI/NEI.

If something doesn't show up in NEI or JEI, if you have BOTH installed then switch between the interface types (under JEI integration) and that sometimes reveals blocks that would otherwise not show.... This happened with mekanism's tanks as only the basic tank shows up in JEI's interface while the others will only show in NEI's interface mode
