Not sure if I'm just dumb, but the space loader seems to be missing from my recipes. I have all other belts and loaders unlocked, but the plain space one is missing so I can't make the deep space loaders.

The item itself definitely exists as I can spawn it. Looking at my research tree, I can see that the other loaders were unlocked with their respective logistic research, but the space one isn't with its corresponding research (space scaffolding). Am I just missing something here?

Are you on SE 0.5, or SE 0.6?

I am using 0.5. Is there a version of this bridge that works better with 0.5? Or should I just update my SE?

0.6 introduces a dedicated tech for belts, so I moved the unlock there, but I forgot to account for 0.5 there.
If you're far into your game, updating might be difficult to reactor for.

If you're planning to stay on 0.5, you might wan to roll back my mod to the last 0.5 version, there won't be any new content for it going forward. only basic backwards compatibility at best.
