[AA] New Peculiar Plumbird every time they show up

Before I go ahead and explain, I have all DLC installed, no mods and I play on PC on the latest game version.

As per usual, I love designing my own NPCs and most of the time I changed completely the look, but also anything else, from gender to sexual orientation etc... I like to create sims and unfortunately the way to change locked NPCs in this game is atrocious. I wish there was an easier way, for instance a UI fot NPC roles PLEASE EA! We have been asking for this for ages... and it still not possible and very frustrating, considering we have to use cheats and hopefully the game decide not to generate new npc for the one you designed. I don't give a dawm about lore either, so thats sad that nowaday NPCs are linked to the lore with their first name directly in game, but I am able to disregard that.

So I tried to change Pruella into Pruello! Changed a few things and detailed the appearances. Normaly, this works, by meeting the NPC, and then using the cheat code ''testingcheats on'' followed by ''cas.fulleditmode''. You got to great the NPC first, and then find a way to invite them to your home and then right click them to modify in CAS, this way, it does not include them in the Active Households and they dont lose their NPC roles!

It worked so far pretty well. The first issue you encounter with Pruella is that she can't be invited afterward, so in order to get around this, you can ask her on a date! She came home and thats where I changed the sim for whatever I feel like the Peculiar Plumbird should be in my game.

It seems like it was working fine, since after the edits, the new Pruello did not lose the costume and on top of that, he had still the specific interactions available for the Peculiar Plumbird. I though it was all good, but then I visited Gibbi gibbi world and found out that the Peculiar Plumbird was now another sim completely. I must precise, in between the moment where I saved the edits and the time I realized the Peculiar Plumbird had changed again, I repared my game on the EA app because I though to try and fix another bug... I am not sure if reparing my game caused that, but no matter, this should not happen.

I want not only a fix and more stability for this problem, but also a permanent solution, such as NPC roles UI update in the very near futur to allow us the player to use imagination and create from scratches the NPC  we want, and that for ALL NPC roles, the Grim reaper, mother nature, the sages, firefigthers etc...

Thank you.
