This corrects some of my tracing errors when I created the Luxemburg empire. Originally I had not intended the Luxemburgs to control Austria, but our group's subsequent claims and assumptions made it impossible to put Austria anywhere else. Austria proper (Upper and Lower) now belong to the Luxemburgs, but Styria and Carniola are in Hungarian territory, while Tirol also controls Salzburg and Carinthia. The Luxemburgs' exclave is called Helfenstein, not whatever-it-was before. Erfurt is now in the correct place. I hope this is acceptable to everyone. The story of Austria's dismemberment should be an interesting one!
(EDIT) An alternative would be to give Upper and/or Lower Austria to Erfurt.
