In my save I've tried looking for the unlock for the small radiator, but it seems it's impossible without cheats. I wanna be able to make them without using cheats pls. Also, nice Mod!

Hello,
It should be possible to craft these from my tests. What exactly makes them impossible to craft?

I'm looking in the recipes that my assemblers can make, and I'm just not seeing it for some reason. I am also not seeing any research requirements for it to unlock. Is there supposed to be a tech that unlocks it?

It seem to not show any unlock requirements when looking in the Factoriopedia, but assemblers say it isn't researched.

Make sure you have space platforms researched. https://imgur.com/zZgVV6O

Oh, might be because I started on Fulgora with Any Planet Start.
