I'm not too concerned with this bug, but I do find it strange. My first play through I was not able to romance Shaundi and I thought the reason was is I accidentally did her loyalty mission before attempting the deed. I beat the game still getting super bullet proof breast Shaundi, and the same ending as if I completed everything, but the achievement did not pop for completing her. I am going through a new game this time I have finished all her missions aside from the loyalty one, and it is still not working. Not too big of a deal, I am just curious if anyone else had this issue and if there is a fix?
