Yeah like @mrsamcan said I think Oinp will refer to score when they issues NOI and once nomination is received a drop of 5 points won’t matter. You might feel better if I said I am also in same boat my birthday just passed and I am in DIP
Same thing happened with me, lost 6 points before getting nominated but received 600 points from the nomination. Losing CRS score due to age after receiving NOI doesn't matter.
