why does it tease me so?

Just when I thought I had finished the first repeat of Chart 1, I find a mistake. Two mistakes. Three. And I Can't Fix It by laddering!!!

One of my new sets of increases only has 7. Another has the appropriate 8. But two others are stuck with 6 even after doing an extra row...

I am going to to have to frog back about 5 or 6 rows at least. *sigh*
