I do not have a prevent building volume. I used Zone Manager to prevent player building.  Is that the issue?  Im not using creative build enabled.  After more review, it acts like it is working in-game.  The maflag on I set for boombox worked.  It powers on every restart and has it in the data file.  I wired the audio out to a laserlight and when I turn the boombox on and off, it turns the laser light off.  However, this IO connection is not in the data file.  I did the same thing at Outpost with a procedural map and had zero issues. It worked exactly as exepcted and stored all the IO connection data properly.

Okay that was it... I added a prevent building sphere and it works now.  Sorry for wasting so much time on a little thing!
