I don't know if anyone already discovered this but i would like to share anyways..
I found a rookie tattoo solution.. all you need to do is change the players "Portrait ID (PortrID)" into any number that is not between 2122 to 2210.. those are the ID's that the rookies were assigned and for some reason when you assigned them to any player, the tattoos that came with the CF disappear... this is also an issue for undrafted D-League callups that patchers assigned to unused ID's between 2122 to 2210... it worked for me, i hoped it works for all of you.. the only downfall is, you lose your rookie portrait, especially if your using portrait patches.. solution to that is to edit the portrait file and assigned the portraits to different ID numbers...
I hope patchers update their portrait patches...
