Hi. Are there any known issues with this scenario in Factorio version 1.0? When I load the scenario, it loads like a normal freeplay map (excluding the "you must launch a rocket" popup at the start).

Scratch that. I did not realise this is available as a mod. Thank you

For everyone who still wants to play this.
So, levels 2-4 throw an error, because they use strory_2.lua script that was deleted since 0.18.20, and you need to manually restore it.
To do this, download an archive of 0.18 version of Factorio (at the end of this post, it's a diff between 1.0 and 0.18.1) and find in data\core\lualib story_2.lua.
Now you either need to place it in JNF_1.0.7.zip\JNF_1.0.7\campaigns\NH\level-02 (also 03 and 04) or you can try to place it in Factorio's data\core\lualib (not tested).
Keep in mind, that there could potentially be other errors.
