Emit is not Emit but someone else....

I started doing the Blast from the Past event today. I tried creating a new character in my current save file. I created a white female, but when I loaded into her apartment, she was a blue skined alien looking sim. I went into cas to try and change her, replaced her with her original look, deleted the alien look, and loaded back into the apartment. Again, she changed back to the alien look. I deleted her from the game and closed out the game and restarted. 

This time I logged into a family on a previous save, that I have played before in the event. This time I made it to the park to meet Emit, and after a time he arrived. But I was suppose to look for a blue-haired white male in blue tron track suit. I was surprised when after searching for awhile, I discovered that Emit was really a black man in althetic wear, almost like Marcus Flex. His name was in normal text, not red like special characters. I exited without saving, to try again.

Now I seen some post concerning cc not showing up or something, so I removed all my cc, only keeping like mccc and ui cheats. So no custom content in my folder now. So this time I started with a brand new save file, created a character, and loaded into Willow Creek starter home. The event said to meet Emit at the park, so I went back to the park, thinking this time blue-haired Emit would be happy to see me. Alas, no blue-haired Emit....instead I got a young white male with glasses in a business suit. This got me very scared, so I jumped out of the game in shock and fear!!

What has happened to poor time traveling Mr. Emit????
