Appreciate that Joe. Not big priority but just to provide a touch more info:
That was my long range scout just passing by those worlds. Its not had any upgrades after launch (Edge of Galaxy or Bust mission ) I had been playing for some hours and it had cruised past those systems without stopping. When I went to check on progress before logging off I observed the colour halos were still present even though the star lables etc had gone.
Instead of logging off I restarted the client and they were gone. My conclusion a graphics buffer didn’t flush out properly someplace. Hope that helps.
