My sim-daughter got a sunburn while on vacation with her family. They've now returned home (where they live on a beach lot) and her sunburn has lasted for days and days.
I read elsewhere that having them sunbathe again can actually be helpful, so I sent her outside for some more bonding time with the sun.
I was thrilled when I saw that her face was tan, with no more burn...BUT shocked to see that the rest of her body is still hot pink! Help!
I had the same issue right after I installed BV. I was like..." Umm is this young man going to ever lose his burn? "
Unfortunately I did it the easy way after 2 weeks of waiting for the young man to come back to normal skin tone and to no avail until I used SimPE.
I don't suggest doing this unless you know what your doing in SimPE though.
Aside from that the only other option you would have is what you tried already. I did that myself thinking that would fix it and although the face changed to Tan the rest of his body did not. So I used SimPE to resolve the issue and as of this day I only subathe my sims if they have it as a want. And even then sometimes I still won't allow it. Just because I don't want to have to deal with logging out of the game to change it back to regular skin tones.
Don't bother trying to do it with SimPE; download the FFS debugger from MATY and choose 'Fix... tans and burns'. Go to the directory for your latest EP, choose hacks and then FFSdebugger. http://www.moreawesomethanyou.com/ffs/
Forcing an error doesn't usually work with stuck burns.
