I have updated Sims Challenge Tracker with beta versions of two new challenges by my friend and business partner, Illusory Thrall! These are updated versions, still being developed. The generations currently showing should be correct, but more generations will be added to these challenges once they are written.
I also added new Un-Collection Goals, which are like collections but aren't tracked as such by the game. (For example, Spirit Dolls or Inventions)
Also, there's a whole bunch of new settings for tracking the details of your sims' gender expressions.
