@Ferpock I believe you are the right person to ask about tattoos in the context of Classic Patch - do you have some 'previous' or 'earlier' versions of playerskin files, before some of the most famous players get a new tattoo?
For example, my Liverpool era Fernando Torres looks like this (first of all, it's very blurry, I wonder if you have a better texture?), with a sleeve he seems to have gotten around 2007
However in that period he had less tattoos
So I'm wondering maybe you have several versions of player tattoo files like this?
For example, when you update Insigne or Kroos, do you maybe save the previous tattoo file?
