I'm not able to get the Loaders to stack. I've enabled the Stacking option for All, I'm running Space Age and I have the Stacking technology researched (albeit via Creative Mode). Am I doing something wrong? Is there anything special I need to do? More information I can provide?

Also found a weird logic check in data.lua, lines 20-22. It's checking for settings.startup["belt_stacking"], which - as far as I can tell - doesn't exist.

Yeah... Brain trip when fixing something else. Thanks for the report. It's fixed now.

Thank you kindly. I can confirm that stacking does work now. I'm guessing the extra check for "belt_stacking" was always failing and returning false on the whole function?
