HOW DO I GET RID OF YAMACHAN?

First off, I tried to turn off Yamachan visits with the statues, naively thinking that would stop him from barging into my home, but it's done exactly nothing. And he keeps barging into my home. He barged into my home last night (in-game time) and HAS. NOT. LEFT. I've tried resetting him (my go-to method of getting rid of him- usually I reset him by right clicking as soon as I see him, he stays there for a moment, then leaves) but it's not working this time. If I could fully delete this thing from the game, I would. I hate him SO much right now.

But, seriously, the amount of random Sims who enter my Sims home is ridiculous. I'm still dealing with a glitch where I can't put grills ANYWHERE on their home lot, lest random Sims start brewing herbal concoctions (this glitch has lasted through multiple patches, it's absurd at this point)
