Black covered Sim

I know that with the new pack coming we have had a lot of bugs in the new update. however, I am having an issue with my sim who has custom tattoos is completely black. on all outfits and I have never had this bug before the update as a lot of sims have custom tattoos. I am aware that a similar issue was reported 5 months ago but it seems so be an issue with early access with the new Nature pack. js might be related but is an ongoing problem that i a unsure how to fix
