I wanted to refine some coal in version 302293 and even if i had coal the recipes vanish. Attached you have the savegame. I will try to load again the game to see if is fixed.
P.E. The savegame is useless After reloading the problem is fixed.
Steps to Reproduce
I don't know. I just played and see that the recipe was vanish. After reload the game the recipes come back.
This issue has been fixed in either a future version or updated in a previous version.
