Lovestruck bugs?

I’m having some issues with the new pack. I have two Sims in a relationship, they’re both highly attracted to each other and “very satisfied” in their relationship, but they keep randomly being mean to each other. Which is even weirder bc my sim has the “proper” trait. But she keeps being mean and mischievous to the point where her partner actually left halfway through a date. And then another bug is that she can’t apologize to them. She keeps having the option to apologize (even though she already did five seconds ago!), and her partner still has a negative sentiment about the bad date (but not the *good* dates they’ve had since then). Could be some cross-pack conflict, the romantic partner in question is Morgyn Ember from the World of Magic pack, and my Sim is a spellcaster herself.
