I've waited patiently for a few months for the Trandoshan species (my favorite!) and they haven't come, so I decided to use some bux, and unlock them and the Tusken Raider.
A week or so later, they still have yet to show up (even as elevator passengers)! So, I decided to run another test and unlock Zabrak, same problem.
I've read a theory that unlocks are the same for all players, and I today unlocked Sullustan, so my big question is; does unlocking in the album enable the species to show up and they still do not, or does it simply add their description and they will show up in the allotted amount of time?
Has anyone even had Trandoshan or Zabrak "randomly" unlock and become available as elevator passengers and/or residents? Or do we all just have to wait until they push the release button for us? My fear is that spending the bux in the album doesn't actually unlock them and locks them out from ever showing up, I have even contemplated restarting my tower out of fear that I had glitched things for myself, but I decided to post here first :)
Thanks for your help!
