[BH] Tattoos not unlocked/relock with skill up

This issue has been persisting whenever my household changes, any new sims that joins including pets suddenly locks tattoos that were once open by both my skill level 10 tattoo artist. My sims adopted a cat and lost access to all the skill level opened tattoos even in custom except for the crystal heart. Why are tattoos tied to the house hold instead of the individual sims? Households should be able to grow and change without affecting the individual unlock achievements. This cannot be resolved I even tried the unlock cheat that works in build and buy. I cannot teach a cat to tattoo I understand they are coded as children and you cannot teach a child to tattoo either so why are tattoos coded to children/pets as part of a household? Also cannot revers their skill level with the cheat so no way to rest their skill to reopen what they already opened
