Ugh. I know how you feel. I had one pattern for a fat quarter quilt that had the wrong measurements for 1/3 of the blocks, then when I figured out how to fix that and got to the block assembly it didn't say what side to stitch one of the blocks onto. When I went to assemble the quilt I found that for the pattern to work I had to pull apart half of the blocks and sew them to the other side of the block!
