Let me add that the "mich" being the very last (or, at least, the penultimate) word of the whole MS, any error would not have passed unnoticed, and the scribe would not have failed to correct it. There is plenty of space between "mi" and "ch" to insert an "L" for "milch" or a gothic "S" for "misch"; in the case if the gothic variant of "S" is inappropriate in the middle of the word, there's no problem to add it on top, as it was commonly done in such cases.
No, it's apparently not an error, it's deliberate.
