@Vanilicious yes, I don't know who made it but it reduces the chance of fated mate to 10% and can be with any type of sim and any gender and with any interaction. Could be mod the sims
So you could get fated mate on a friendly/ funny etc interaction with any type of sim. Not sure if it applies to already involved sims married/ partner etc
I opted out because I don't want it happening on any type of interaction though lessening the chances to 10% is nice I would just prefer an option to actually defy fate all together
