I was
I am in a similar process. I dropped points cause of age and had to retake the IELTS which didnt go well. However if your points at the time of AOR to OINP are above the cut off, it should be fine afaik. After your your AOR for OINP , all that matters is that you have 67 points in express entry and your profile is valid. You could have 200 points after OINP AOR and it wont matter. Those points become irrelevant after OINP AOR. However until AOR you have to have those points. These things might add slight delays but definitely not a cause for rejection. Nominations happen via express entry in OINP but once your AOR is done its natural many people drop points due to various reasons.
