data-final-fixes.lua:552:attempt to concatenate local "result" a nil value. Not sure what I've done to cause it.

https://www.dropbox.com/s/e7wxk3qp8cenqv2/Skjermbilde%202016-07-26%2001.06.38.png?dl=0 Screenshot of the error. My list of mods is huge, and many of them are made/ updated by me, but no one have had any issues untill I installed this mod. Just ask if there is any more info I can give :)

That error is caused by a recipe you have, but which produces no results! I don't test for this.

I don't understand why anybody would have a recipe that produces nothing?

I'd love to know what mod you have which does this, so I can test and debug.

Oh do I? What... I dont know where and how but I'm sure I havnt made a recipe without results haha

Heres my pack https://www.dropbox.com/s/g86wkcskdbqk09j/ValeratesModPack.rar?dl=0

Theres way to much edites and I am honestly amazed it even launches and works :) So, if you intend to find the broken recipee, good luck for I have looked for hours now and found nothing :<

I am assuming that this is a bug. An item and recipe that give this error are an 'alien-atrifact-fragment' in the ExtraStuff mod. Below (for my reference) is a dump of the item and its recipe.

{
  flags = {
    "goes-to-main-inventory"
  } --[[table: 000000000EADC580]],
  icon = "__ExtraStuff__/graphics/small-alien-artifact.png",
  name = "alien-artifact-fragment",
  order = "h",
  stack_size = 200,
  subgroup = "intermediate-misc",
  type = "item"
} --[[table: 000000000EAD51A0]]{
  enabled = "true",
  ingredients = {
    {
      "alien-artifact",
      1
    } --[[table: 000000000EACF5C0]]
  } --[[table: 000000000EACF560]],
  name = "alien-artifact-fragment",
  order = "h",
  results = {
    {
      "alien-artifact-fragment",
      20
    } --[[table: 000000000EACF680]]
  } --[[table: 000000000EACF620]],
  subgroup = "intermediate-misc",
  type = "recipe"
} --[[table: 000000000EACF500]]

The error is being caused by the Extra Stuff (and others in your list) mods not following the strict rules about how results should be formatted in recipes.

http://lua-api.factorio.com/latest/Concepts.html#Product

My code assumes that those rules are being followed, but in the example above the recipe does not include the 'type', or add any 'name' or ' amount' labels to the results.

'Extra Stuff' is not on the mod portal, 'DyTech' also gives this error but the author has not published a v0.13 version yet. Neither are therefore 'official' so I cannot offer to fix this issue until those mods are avaialble officially and follow the formats on the above link.

Will leave this issue open, but will not fix.

Actually, I've decided to fix this in v0.13.18
