My sim has become Yamachan and I can't get rid of it?

[Pb7697Ab02]

I have created an avatar for my sims boyfriend who's mom has turned into Yamachan. She is the ONLY sim character that is given the Yamachan suit. If I delete her and add her back onto the game, She's turn into Yamachan. Like the game won't turn any NPC into a Yamachan beside my sim character.It's so annoying because I can't do anything to get rid of it. What can I do?

If you delete the sim that has the Yamachan role and immediately add that sim back that already has the Yamachan role it shouldn't surprise you she will still have the role. You can instead add her to a played household. That should cause her to lose her Yamachan role and the game will create a new NPC with the Yamachan role.
