I have added the save. I hope you can see what's up. I am kinda stuck this way.

Did an uninstall en a re-install. Still the same issue. I cannot make sulfuric acid in the chemical plant.

I have deleted the mods that I loaded for a multiplayer map. Could that have had an impact?

I do not think I have any mods loaded, just the base mod. Should there be?

Hi,

As I am setting up Sulfuric acid production, I am unable to select sulfuric acid in the chemical plant. I have researched the sulfur processing technology.
As far as I know I should be able to select it. Can you help me with that?
