So out of interest, because I hate this ship and need to fix it so can't do these things atm... are these POI's that you discover like Barnacles via DSS? Or are they "flora" and need to be searched out like for exobiology?I'd check the Codex - under Thargoids ....
I very briefly went through a bunch of atmo planets in a tharg controlled system and couldn't find Thargoid (POI) signals on any of them, but didn't go so far as to search planets with Biological (exobiology) signals.
