Honestly no. All I did was mined the top individual layer of dirt, then the one underneath it that had water flowing after they had finished the top layer. After loading that save and working on another area, I didn’t get the error, but instead got a couple more artifacts like the one shown next to the Hearthling.
And to make things funnier, I decided to reload the other save file that had been a previous 22.5 save, and the water is working better in that save than the new game.
Only other thing, but I doubt it would effect it, is that I’m running Home Sweet Home.
