Thanks, now it works. It was hidden, because I turned on the "hide obsolete worker actions" option and for some reason, it is considered obsolete when it comes available. The sea tunnels have the same problem and I think this is fixed now.
Also, the Path that can connect cities on the moon has the same issue... Do you think it is worth adding a new type of road for that?
The Cislunar Trajectory can also not be build on Orbit Terrain since the Cislunar Worker can't access that. So the "Road" only works between the colonies, but not as a connection to earth, is that intented?
Also I observed a mid turn lag (10sec) after I started colonizing the Cislunar Space...
Then there is a small issue with pathing. I select a Planetary settler and tell it to go to mars. And it does. Then, the same turn, I select another one and tell it to go to the same location, it won't. If I tell it to go 2 steps away from it, there is no problem and then there is no problem when I go from that spot to the initival target plot... strange!
I noticed that your autobuildings have a cost. Normally, they were at -1 cost I think so they can't be build at all. I think this could be an issue if you sell them; they probably give you money and are rebuild next turn. If you can sell autobuildings... But even if it would probably not worth it do to this...
I've seen that your Venus Solar Array is more expensive than the Martian one, while giving the same output. It turns out to take the same amount of turns since the venus colony gives more

I was wondering if you considered giving them different outputs in the future since solar panels around venus are more efficient than mars due to the closer distance to the sun.
The Lunar Mining Outpost is an improvment that should be buildable by the Construction Ship. Right now, it's not. Since I don't have SVN access now, might I ask you to fix that please?
Regarding the costing of your buildings:
- Aerogel Shilding only takes 1 turn when it comes available. Could use a 5-10 times increase in cost.
- Cislunar Refuel Station takes 1,5 times
- Asteroidmine costed 0,7 turns
- Mars Mine (3) turns, Geothermal thingy, the Geothermal Lab and the Water thingy (at Planetary Exctraction) all take 3 turns, maybe 2 after the Mine is built.
As always, really great mod. It adds so much to the game! I'm also highly pleased how well my lunar mod fits in it, thank you a lot!
