Hi! Just noticed that the "Rail boxing" recipe requires 0 ingredients to produce 4 boxes of rails.

I'm not able to reproduce this. Could you take a screenshot of what the recipe looks like, and provide a list of the mods you have enabled and their versions? For me the rail boxing recipe takes 20 rail to produce 4 boxes. I also checked the "boxed" production versions and the unboxing version. It all looks right for me. There could be some bad interaction with other mods if you're still seeing a problem.

Here you go:

It's strange because no other recipes are affected, and the recipe is only touched by Nullius, Angel's and Bob's.

If it's not a general issue that other's are facing, don't worry about it, we're actually almost through our playthroug, and it hasn't had a major impact on our game. Been awesome!

It appears that Bob's Function Library 1.1.3 introduced this bug, and then 1.1.4 fixed it. So I'd recommend upgrading that mod to the latest version. It also works with 1.1.2. I've tested it with all 3 versions, and with 1.1.3 I can reproduce the rail box bug you're seeing, but not the other two. This makes sense given the change log in that mod about a bug with rail being removed from a recipe.

Ah perfect, makes sense, thank you for investigating!
