Penetrating radar cybernetic not working

[Former user]

The cybernetic does not increase visibility at all and appears to have no effect. Tested with toggling it on and off with and without a light source and could only see with a light source as you would do normally without the cybernetic

From a new game as First Gardener, wishing 'license', then 'penetrating radar', collecting radar, wishing 'idall', wishing 'becoming nook', using nook to install radar results in a functional penetrating radar. Whatever you're seeing, it isn't a matter of penetrating radar simply not working, and whatever other conditions are necessary to generate the failure will need to be discovered in order to debug it. (There's also the possibility of it being a mod issue if you have mods installed.)
