I don't know about that. Comparing her 2014 season to 2015. . . looks like she started a week earlier this year and decided to take a breather before mid May. Jonathan Brownlee also took a pass on South Africa after doing the same races I believe. Honestly, the location is such an outlier, that I can't fault someone for passing on it.
From her blog:
"Thank you to all my sponsors for their support, Jamie and Patrick for their daily investments, USA Triathlon, and my family, friends, and fans. Without your help this journey would not be possible. I will miss the next WTS race in Cape Town. I will get in a good block of training before heading to Yokohama for the 5th WTS of 2015 on May 16th."
