My borders recently expanded and I managed to take control of the system of another empire. I need to build an observation station on a planet but the other empire already built one.

I can disband a mining station, but the option is not available for an observation post.

How can I remove the current space station and build my own?

  • @RavenDreamer it is in a sector owned by me

That's because the observation post actually still belongs to the other empire. Ownership of these is not transferred when system control changes. No idea, whether it's a bug or intentional.

The only option is to go to war again and destroy the observation post.

    Well that seems like a serious problem. That observation post can take control of the planet, giving the system back to the original owner.

    Not sure when it changed, but this seems to have shifted in a subsequent patch. Observation posts now change hands, I think (and, interestingly, you inherit the old owner's policy - I aquired an ob post and almost immediately afterwards had it complete technological enlightenment... a bit of a surprise!)

  • Yes, this behavior seemed to have changed at some point in the last 2.5 years because I just inherited an observation outpost when I took a bunch of nearby systems.
