The only hack I have that I think even messes with relationship decay(and I'm probably wrong) is Pescado's phone hack. And I did miss updating that and it still happened after I updated it. I've got all the hack type of downloads pretty well organized into subfolders. I had a couple duplicate hair meshes, no duplicate hacks. According to Paladins Hack Checker, I had a couple of similar mailbox hacks and vampire interaction hacks. Nothing fighting over relationship score. I have gunmods cameras, some simslice/wintermuteai1 stuff(nothing to do with relationships except maybe the "surprise reactions" encoded in a couple of those).
The only thing I have by Monique is the work bring home friend dialogue. And I updated that earlier. Other than that the only behind the scenes game mods I have are from here. And outside of missing the phone hack update I went over the ones from here very carefully to make sure I got all the ones that were updated for pets and got rid of the ones that were listed not compatible. I'm gonna go through and check again, but I suppose I'm going to end up pulling it all out and adding em back one at a time to see what it is. Who knows, with this game it could be anything
Thanks for trying to help anyway!
