So i witnessed that when you take out an AI empire by taking only their planets without taking all systems, the remaining systems are greyed out afterwards and can be surveyd.
Something similar should happen to also those systems you conquer with the exception ofc of those objects already having stations on them or being inhabited. Though even these may still have a chance to find new relic sites would be nice.

Is this something your mod is doing or maybe doing in a future iteration?
Does this mod work with 2.6.2?

Thanks for the feedback, lets wait and see if anyone else has the same issues. The goals of this mod may no longer be achievable with the current game version.

not sure if this is because of the mod but even if I close my borders the ai can send in constructors and science ships. even if the Ai is my rival. might not be your mod though. great otherwise

I hope the mod works, gonna try it.
