I tried freetranslator, but got nothing. I was reading a book in the library and came across this untranslated word, and had no idea what it meant. It isn't really a "bug" in the sense there is no real problem.
If i understood you right, you want to know what sattmacher means?
In the game the potion "sattmacher" is the same like food potion. But it "isn´t" correct translated. The word "satt" means in fact "to be full/ have had enough"
