In my current run, i saw some Lightnings on my sensors, which used to be impossible.
After seeing i didn't have the Lightning analysis (and no prototype analyses at all, as i forgot to get Zh's), i checked Cog-Minder.
The Lightning analysis states that it "remains completely undetectable by any known non-visual sensors", but its scan cloak was lowered to 4, which is detectable with an Exp. Signal Interpreter.
