I tried this in both Horizons and Odyssey with both Neutron Stars and White Dwarfs, and couldn't get the EZ to appear for any of them. I tried toggling orbit lines on and off - no difference. I tried various SuperCruise speeds - no difference.
I don't mean to doubt you @Sentenza but was that screenshot definitely taken today? If so, what setup are you using? Console or PC?
If it's PC, can you share your graphics settings so I can try and recreate the setup here?
As an aside, FDev have confirmed the issue, so they do acknowledge there is a bug here. Personally I'm just keen to see what conditions are required to make it work at all.
Yes it was taken right before posting, in fact it is part of a recording. I'm on PC on an old rig, setup at 1980x1020 borderless window on high.
The weird part is saturday and sunday the zone was always visible, I know because I was carrying around long range vip passengers and I was cone boosting all the time. Maybe it can be dependent on the stars?
