TLDR Married couple can't socialize with eachother, possibly mod related


In my most recent playthrough, I started out with 2 pawns. The two pawns are Nicole and Arty. For some reason, in the 3 long years they have been on this planet, they've never had more than pleasantries and small-talk. They can socialize with (some, about 75%) other pawns, but never with eachother. Perhaps it has something to do with their traits, which are:

Nicole:
Psychically dull
Neurotic

Arty:
Heavy Sleeper
Outdoorsy
Kind

Neither has social disabled. I've tried sending them on a caravan and having them rest, as it says pawns can socialize then. I've tried sending them to a different map. (both of the former at the same time and on their own). The only thing I can think of is that it's mod related, so here's my list of mods. I'm wondering if anyone else has had this problem and identified the issue; it seems hard to recreate, but I'll re-copy the seed, coordinates, and starting conditions and make a new game for every mod if it comes down to it.

Anyways, here's my mods in load order, and I've bolded the ones I think *might* cause a problem as I go:

Game version: 1.1.2654
Harmony Lib v2.0.2.0. mod v1.4.0

Harmony, Core, Hugslib, Psychology (unofficial 1.1/1.2), Animal Variety Coats, Directly Abandon Settlement, Room Sense, EdB Prepare Carefully, Conduit Deconstruct, Pick Up And Haul, Industrial Rollers, More Planning, Power Logic, LWM's Deep Storage, Damage Indicators [1.2], Expanded Roofing, LinkableDoors (unofficial), Centralized Climate Control (Continued), More Map Sizes, Realistic Planets - Fan Update, Progress Renderer, Miscellaneous 'CORE', Misc. Turretbase, Objects, Expanded Prosthetics and Organ Engineering, Medical Tab, RT Fuse, A Dog Said... Animal Prosthetics, Locks, Animals Logic, Hospitality, Colony Manager, Misc. MapGenerator, Animal Tab, Blueprints, Relations Tab, Mad Skills, Camera+, What Is My Purpose, RT Solar Flare Shield, Parallel Power Grid (Parallel Conduits), More Linkables, Pharmacist, RenameColony, Bounded Roof Build Tool, Color Coded Mood Bar, Work Tab, Deconstruct First, Remote Tech, Orbital Animal Traders, Humanoid Alien Races 2.0, Android Tiers, Area Unlocker, Save Our Ship 2, [JDS] Simple Storage, [SYR] Set Up Camp, Backup Power, Smarter Construction, Rimatomics, RandomPlus, Gloomy Furniture, Rimvibes


I don't think it's humanoid alien races or android tiers because Arty is able to socialize perfectly fine with an android in the colony. Hospitality might mess with it somehow, I'll check that first probably.

Thanks for your time and help
