I got it working! I just wanted to stop by to let you know that thanks to your v2.0 mod, ACR 2.0 now works correctly with my game! I realised somewhere along the way that your ages are the same as mine - divided by 3. Once I figured out how to add a multiplier to your controller, I simply set it to divide by 3, with everything else held constant. As far as I can see, it works great, as my newly made adult female has a 62% chance to TFB, while her newly created elder mother is showing 0% which I think is correct as well! It also has their ages correct at 205 and 560 days old respectively. I can't thank you enough!
Finally managed it!
