Pulvis Production building (opened by Relativistic Economics research in Era 2) seems to give bonuses for Empire (instead of  System as intended), which sooner or later breaks buyout system completely. With enough Pulvis Production buildings, I get "You already bought out this construction" for all buildings and ships, and no way to buy out.

Just wanted to know if anyone else noticed that. 

I'm using debug menus to go through the game faster, so this might just be something screwed up in my game.
