Not sure why. Tried it with absolutely everything not mandatory turned off. Tried it with manual install. The file is there and named identically in my mod download.

What is your Factorio version? It works just fine on 2.0.72. This looks like an error with the game's data rather than the mod. Try reinstalling Factorio (verify integrity of game files through Steam, or another way). As far as I can tell, the error could only be happening if something's wrong with turbo belt data in the Space Age DLC content on your computer. Otherwise, I'm not sure what else could be causing this. And you do have the Space Age DLC, right? I noticed my mod doesn't say "Space Age mod" on it even though it requires "space-age" as a mod. Never figured out how to fix that. Wondering if somehow that's the issue.

Yeah I'm on latest space age through steam, nothing fancy there. I'll try reinstalling and update here if that worked, thank you.

I figured out how to flag my mod as Space Age dependent. Hopefully this somehow fixes your issue on the next mod update (1.2.0, coming within the next 24 hours most likely).
