With that much superfat, it will be tough to make a lye-heavy soap. Cold process soap can be zappy for a few days after making, so it's best to not rush into zap testing -- your soap is an example of why a bit of patience is good --it's too easy to draw the wrong conclusions from zap testing too early. If your goal is to verify the soap is safe for use on the skin, I suggest waiting at least a few days to a week before zap testing.
"...made this recipe just the day before no issues at all- except that I soaped cooler than normal and used dry milk to anchor the scent (ran out if clay)...."
So think about it ... you soaped cooler so it will take longer to fully finish saponifying. And you added milk which means there are milk sugars and protein in this batch that weren't in the previous batch. Two significant changes to this batch compared to the one you made the day before. It doesn't make sense to assume this batch will behave the same as the other batch.
FWIW, clay, activated charcoal, milk, etc. etc. etc. don't work to "anchor" a scent, no matter what the internet says.
To make fragrance last longer in soap, use scents that have proven "sticking power" in soap. And add enough fragrance, within safe use limitations, so it's as strong as possible to start with.
If using EOs, it's important to formulate an EO blend that includes base note EOs, not just short-lived top notes and medium-lived middle/heart notes. Base note EOs are usually resins, spices, and woods -- patchouli is a base note, for example.
