To edit your created superstar or diva's abilities, restart your career with the 
same superstar or diva you used. Note: You will lose all your gained abilities. 
You will also take longer to gain Resiliency if your attributes are higher, and 
if you are above 80 overall, you will not be able to get Durability. Always 
create doubles of a CAW or CAS immediately after making them. By doing this you 
can start over with the unused copy and gain Resiliency and Durability in a 
quicker amount of time if you end up gaining unwanted abilities.
