So, I have done what you said here. I have also added BuildCraft, IndustrianCraft, RedPower, Forestry, and ComputerCraft to OP, and to TownyAdmin. I made sure that they were all listed under the fakeid section. My tekkit still is not working with towny installed but works fine without it. I am running Tekkit 3.1.2 and Towny 0.81.0.0
