I regenerated the code. And while it didn’t fix the issue, I did figure out what happened:
Under Custom Special Ability Control Layers>Special Ability 2, I had Toggle Rain and Lightning Mode (Random Bolt) turned on. It turned on the preview saber despite my having turned it off earlier.
Changed it to Toggle Rain and Lightning Mode (Alternate Bolt) and the preview saber retracted. Pasted that and everything worked.
Also had some issues with PreOn and PostOff but saw this thread and fixed it by making a preon1.wav and pstoff1.wav.
Thank you @profezzorn and @Fett263 for you help!
