I think it was one of those materials I liked to introduce by trading and let the people learn to produce it later. There are pictures of a historical ashery in my folder, so that must have been the plan. At least there is an option to produce potash in the glass factory.. if you drop down the menu. A bit inconvenient to switch from time to time but the alternative to trading.
Thanks! That’s what I needed to know. I knew I was overlooking something!And thanks again for this update–I enjoyed the original North mod a lot, and now that I am back to playing, it’s great to have some new content and challenges.
