Blueprints not importing correctly.
Blueprints not importing correctly.
I downloaded a blueprint from Nilaus and when i import it it doesn't import one of the foundry's. On Factorio Bin when i import it.
Re: Blueprints not importing correctly.
Sharing the Blueprint string and your save game would help a lot. 
Re: Blueprints not importing correctly.
This error occurs because of an internal prototype rename between game versions (or missing Space Age mod data when importing into base 2.0): Factorio 2.1 Recipe Rename.
In Factorio 2.1+, the internal recipe names were changed from molten-iron and molten-copper to iron-ore-melting and copper-ore-melting.
If you try to import an older 2.0 blueprint referencing the legacy internal recipe identifiers into a newer version, the game throws unknown recipe name and strips the recipe/entity.
You can add a foundry and set the recipe manually on the ship after you paste the blueprint.
I think you are playing 2.1 just like me and I have run into same issue. This solved it for me.
