Hi. In my game I have recently wiped out some precursors(I think they were precursors because the communication with them has proven impossible and they didn't leave any lifepods when their ships blowed up.
) in a system and sent in a geosurvey vessel to check out the planets for ruins. When my geosurvey ship moved to the first planet of the system it registered a thermal 5 population belonging to the precursors. So what is this population? Somwhere I've read that thermals pick up industrial machinery on a planet, so can it be some abandoned industrial stuff?
Or some other nasty surprise from the precursors?
