Not sure if this was a loading error but the radar limit was set to 50.000043 when I jumped into the sector making it impossible to lock onto the roids. I will check it again when I go back.

I should mention its a high density fogged sector.

I jumped back in / relogged and the radar was still limited to 50 m.
I forgot to mention visibility was not affected.

This is the only sector I have seen this in.
Suspect a zero was omitted in the data file.
