Radar range seems to be totally zero in Deneb G-6. I expect a limited range given the fog, but this seems to be on the wrong side of the decimal place. I can be right on top of an ice crystal and not be able to target it.

I can still target ships of group members, or my own capship, but not anything else.

Checked half a dozen other ice sectors in Deneb and they seem to be OK, so maybe this is just a problem in Deneb G-6.
