Just a heads up, it would appear that the author of the required mod "Guv's Smoke and Gunpowder Mod" may be considering taking down their mod as they no longer maintain it. No idea if this would break the Deithland mod, but it might be worth finding a different smoke mod or incorporating it into Deithland if possible.
