Permanent Ailment Marks

Hi there,

I'd like to bring about a new bug I've found after the last patch (July 25). 

My sim has the marks of an ailment, her face is covered with random small red dots, but she is completely healthy. It's not a feature from CAS, where I've tried to remove the marks that way. I've even tried making her to eat the cure (the Sonic Sinuses Cure), but all I got was a temporary angry mood because she had comsumed a cure without any ailment.

Could this be a bug?. Are there somebody who has too?

I must add that she's a disguised occult: an alien (the alien version has no problem). I've never had a mod or cc. This started after installing the new patch; I was in another household when installing though.
