Well, here I am again
I'm right now in
Eolls Byoea KX-R d5-7 system. It is
reported by EDSM as the only Trojan Belt's system with metallic crystals, and it is wrong, because in game this system belongs to the
Sagittarius-Carina Arm region. But this is, of course, problem with EDSM's algorithms.
However in game the system is not bug-free: there are peduncle trees and pods here (as well as all over the region), but in this particular system they are bugged and don't scan for the Codex.
UPD. There, actually, were two systems, in the Trojan Belt,
reported by EDSM as having signs of NSPs, the second one was
Sphaulua CN-H d11-8 with proto-lagrange cloud. In game this system belongs to the
Dryman's point. However peduncle trees and pods here are also bugged and don't scan for the Codex.
I wonder whether the fact, that both systems, bugged in EDSM, are also bugged in game, is supposed to mean something, or is this all just a coincidence
