Doesn't work for me either. There's another way. Click the + on any species, and find the deal where u buy a level 10 dino for some bucks, now search '[species ID];10' There will be quite a few.
Now do [species ID] only, and click refine. click on each of them and click Go to.
Find the one that has '10' on the line below the ID line.
Modify the 10 line, then refresh the deal to see if it's changed.
Once you identified the right line of code, you can change the species ID to get what u want. Go to the other species in the cage or the center, click find and you'' see what u want to get
Note: The deal will be moved to that species' interface. Meaning that you cannot get a dino that has not been introduced. Which is good anyway, since those are illegal and they'll ban your account if you have them
