Possible bug: I added your mod and this showed up on start: Failed to load mods. Error in assingedID: item with name 'infused-military-science-pack' does not exist. It was removed by infused-science-forked-again.
Source: incinerate_military-science-pack (recipe).
Seems to be a conflict between these two.
hardCrafting(1.0.6)
infused-science-forked-again(1.1.91)

Hey thanks for pointing this out, ill see if I can do anything, no promises, can you please link which mod youre referring to?

In my testing of HardCrafting 1 and 2 it seems to load fine, just no bonus modded packs.
Are you trying to add it to a game save in progress? Do you have any other tech tree altering mods added?
As is I cant reproduce the error easily.

thanks.

hard crafting is the mod i was talking about. whether there is another mod conflicting with it. it did not say. thanks for the mod.
