I am working on instructions using Bricksmith followed up with LPub and I am noticing that the Flexible element Lsynth Power Functions Cable with LSynth Constraint Part - Type 6 - "Power Functions Cable" is not rendering in LPub, but the LSynth Fiber Optics Cable with Synth Constraint Part - Type 7 - "RCX Cable" is. I am running LPub version 4.0.0.10 and Bricksmith version 3.0. Any help would be appreciated.
