my mods are: toolbar, ERS, CLS, Contracts Window, Orbital Science, Editor Extensions, Firesplitter, JSI, KAS, Hyperedit, KIS, KW Rocketry, Infernal Robotics, MechJeb, Procedural Fairings, SCANSat, Science Alert, TAC Fuel Balancer, TweakScale and Universal Storage. ModuleManager 2.6.6 is installed. I don't know why it's doing it either. If it showed up under the Pods parts list I could maybe understand. I'll see if it does it again.
