Recently whenever I travel to Sixam the alien sim's heads are invisible aside from their teeth which are just floating where I assume their mouths should be. I thought it might have been a broken mod/CC or an issue with the save file I was using but when I removed all my mods and visited Sixam on a new save the alien sims still looked the same. I went into CAS and added an alien sim to my household and he looked fine, I took him to Sixam and he didn't have the issue at all. So I added one of the broken alien sims to my household and put them into their disguise and the disguise had no issues, it was the same thing when I put them in CAS they still looked normal but when I went back to Sixam thinking the issue was fixed they were still broken.
