I love this pack, but I don't love the fated mate system and there seems to be no way around it unless you never flirt (autonomously or not) with another werewolf. I have a serial romantic weresim...
Zero made a mod that removes fated mates. I have to check and see if it will still let you manually assign the relbit with cheating, and if so, then we can just choose our own fated mates. Aside from how they handled this tense moodlet business, the entire concept of fated mates as it stands in Sims 4 seems so lackluster as well because being fated mates with someone doesn't really add much, as far as I can tell, even if you WANT the sims involved to be fated.
