In the part where Phredd the gatekeeper is looking through old relics to find Loamhedge, he says [in those days the abbot was old MORDALFUS] but in the very next sentence he says [MORDALPHUS was a great abbot] Two different spellings back-to-back. A big slip-up on the editors side of it
What I have to say doesn't really have anything to do with the book. Do you remember the survey before you submitted this slip-up? It said that if your slip-up was a spelling mistake, then it was too trivial. Why did you submit a slip-up when they didn't want you to?
