{Duplicate report of Failed to Load mod as bug is still existing} - Same bug still present.

Failed to load mods: reverse-factory/func.lua:327: attempt to concatenate a nil value
stack traceback:
reverse-factory/func.lua:327: in function 'makeFluidItem'

I can see you have attempted to fix it in the previous post I have just created this duplicate as it was marked as 'fixed?'. Great stuff so far thanks for all the work.

No problem; were you using either of the mods mentioned in the previous thread? Plutonium Energy or Concatenated Solar? If not, do you know if you have any other mods that add fluids? Failing that, I would need a modlist to test where the issue might be coming from

Hey there - I'm sneaking into this thread as I get the same error while loading. If you need anything else just tell me/us.
Plutonium Energy is loaded as well.

I get the same error, mate. I only use the Plutonium Energy.

That's odd, I'm not getting any errors while running with just Plutonium Energy. Are you using any non-default settings? Sure no other mods are enabled, apart from my version of stdlib, this mod, and Plutonium Energy?

EDIT: I think I've narrowed it down; Plutonium Energy without Space Age works fine. Plutonium Energy with Space Age causes the error. I might have to re-define what "vanilla" means when debugging

I forgot that order was optional, and would appear as nil instead of an empty string when attempting to access it, hence the concatenate nil error. I was trying to append the original order to the ice and ice-melting orders for items and recipes respectively, so the crafting menu would look clean (without space age, the value would just be copied directly, which works even if nil value)

Should be fixed now, as of v9.0.4, with or without space age. I haven't tested any of the other mods in the list, but I assume it was the same issue with any mod that added a fluid without an order, while space age was enabled.

Yup all fixed. thank you.

All fixed. Thanks mate!!

Can confirm both Plutonium Energy and Cheese's Concentrated Solar no longer cause a loading conflict with your mod. Thanks for the super quick response and fix!!

Same from me. Functional and working. Thanks for the quick fix and help!
