You may have already tried this, but did you delete the localthumbcache when you removed your mods? That sometimes helps refresh internal things. You could also try saving as for a test save, then jumping ahead to the next week to see if the game just needed to time refresh for the next scheduled Accolades (i.e. let it regenerate on the calendar).
Personally, I'd stick with the modded game that you're happy with and delay infants for a week or two, then reassess the decision based on whether your mods have updated. It's not a terrible idea to wait a few days anyway just in case the update introduces some unexpected weirdness that would render it unplayable, with or without mods.
Edit: sorry, just saw you already did the localthumbcache. This is a rough choice
