VeraPlus was acting as Primary controller. When Primary was switched back to GE-45601, all Key assignments to existing Z-wave were wiped out. This was not a Copy, only a move of Primary to GE-45601.
Have not run into GE-45601 Key assignments being wiped out by swap of Primary between other Z-wave controllers (another GE-45601, miniMote, USB stick).
