Stumped By Victorian Ruby

I know this pattern has been completed and I don't remember any comment on mistakes in the pattern except the one on the errata sheet by Knitter's. I can't get past row 28. I've checked and rechecked my stitches, walked away from the pattern and rechecked again. I have 51 sts at the end of row 28. I end up 1 st short on row 29. I count 9 decreases on row 29 and 9 increases on row 29 so how can the pattern increase by one stitch to 52 stitches?

I am so frustrated. Any help so appreciated.
