After more testing, the issue is somewhere between the game auto saving at the start of a new day and loading after restarting the game. Edited previous post with details to reproduce this.
2 other issues, not worth creating a new thread
- new crafting jobs are added right away, with the default settings, before one can even choose the recipe
* it could be more intuitive if the recipe was added only after choosing the item to craft
- with multiple modules of the same kind (2 smelters) the possible recipes are shown for each of them
* when adding new job you can see multiple metal plates, beams, one for each smelter connected
