They simply won't appear on Sims which have already been created.
I have already tried deleting all cache files located in the The Sims 3 folder, but to no avail.
This obviously means that the mod is working, but it won't refresh the Sims which already exist. Anyways, the problem is that the Sims which I have already created will not take on the new default skin which I downloaded, though Sims which I create do have them. Hello everyone! I know that this doesn't necessarily have anything to do with NRAAS mods, but I am unsure as to who to ask for assistance in this endeavor of mine.
