before I marry someone I move them in as a roommate. After that roommates start coming in the house occasionally, and I don't know how to get rid of them. I click on them, click Roommate and click Dismiss Roommate and they leave. Now theres an invisible chick in my house and I don't know how to get rid of her cause it wont let me click on her. If anyone knows how to get rid of the roommate problem too that would help lol thanks. I don't know if this is on the right forum or not

I read house as 'head' and got majorly concerned...

You might be able to get your local priest to exorcise it.

Oops, sorry I only read the thread title

What would Buffy do?

If resetsim doesn't work try moving out and move back into the house, it usually works for me.

The phone has an option called "Roommate services" inside the Real Estate and Travel menu. You can stop the roommates from there. It should get rid of the invisible girl too.

If a Sim is invisible (and thought bubbles appear from the ground), it's usually because they have invalid or corrupted outfits. Several tricks have been shown to fix this, but I don't recall any of them. :/ I just knew the cause.

there is also this mod http://www.den.simlogical.com/denfo...hp?topic=1450.0 but its only referred to work with patch 1.50 by the creator so better try to contact Consort and ask if its still ok for patches beyond 1.50.
hopefully one of these suggestions work for you ;-)

Set of some fireworks inside the house, that usually does the trick.

I found the dismiss roommate option in the phone lol. First she died on my kitchen floor invisibly. then I reloaded and kicked her out of the house

Or better yet, set off an "electrical fire" it'll solve you're problem and you will get some extra money from insurance.

You should have called the Ghostbusters!
