Can't build last SS Booster

[the shah of iran]

So I'm playing as Babylon and I'm going for a science victory. Pretty simple it's my first time I've tried to do this type of victory. I built the SS cockpit, SS engine, and one SS booster before realizing I needed 3 SS boosters. Fine I thought I have enough money to buy one more and produce the other in the next city. So i purchase one SS booster in my capital and go to my other city to build the other one. But the city I wanted to build it in doesn't have it in the build menu, and neither of my other cities do either. I launched the 2nd SS booster but I still can't purchase or build another SS booster. I have no idea what's wrong and I'm playing with no mods.

Maybe you've ran out of the stuff you need to build space ship parts?

Usually this happens when another victory type has been achieved i.e. one more turn; have you or another Civ already achieved a different victory type?

I don't think you can purchase them.

you can purchase ss parts with the freedom ideology tier 3

OK - I didn't know that.

Migtht explain a couple of times I've lost when going for a Domination Win. I think a Civ is completey beat, so let him have peace when maybe he only has one Rocket part built, and one city left.

What I thought was a complete complete cheat - cos they won space race with their one City left, before I could even attack them again.

It's wrong in my opinion, that when you take someone's city with their rocket in, it doesn't destory it and they have to start again. This is a big bias in favour of Space Race over Domination Victory.

Hey, problem for me was i'd already built three of them. Went into the military tab, found one embarked across the map - brought it back. Doesn't let you build more when you already have enough.
