Okay, I appreciate that The Sims 4 allows you to select "they/them" pronouns for a Sim when creating them (as I did for the alien Sim in my "Cryptid Buddies" household[1]), but... the display of said pronouns in-game is completely broken in a bunch of places. As in, far too often, you'll see a "their" when it's supposed to be "them," or "them" when it should be "their," or either of those when it's supposed to be "they," or even if the right pronoun is used, the verb will be wrong, e.g. "they is" instead of "they are," etc. Things like that. It makes sense that it would be that way, if all EA did was run an automated search on things like he/she, him/her, and his/her and just replaced it with they/them/their or whatever without bothering to have a human look at the results and edit them appropriately, because in such cases, it was inevitable that the wrong word would be used. Meh, it's obviously not a dealbreaker or anything, and again I'm glad that they at least tried to do something good, but the implementation of it leaves a fair bit to be desired.
[1] - It's a household that I started with a vampire, a werewolf, a spellcaster, a mermaid, and an alien, with the alien later building a Servo. At some point, I'll probably adopt a (normal, human) baby and later make them into a PlantSim. There's also a Patchy living in the greenhouse, though he's not technically part of the household itself, as I can't control him. And, for what it's worth, some of the above Sims are friends with both Father Winter and the Grim Reaper. None of them have met a Flower Bunny yet, though. Also, I haven't bothered with ghosts much, other than using in-game abilities (or sometimes just cheats) to bring back to life a few NPC Sims that had died.
