So, I am trying to make a mod to enable the werewolf 'Hunt' interaction for child sims, and make a child version of the adult animation 'a_werewolf_huntSniff_x' so that the child sims will not stretch when they hunt.
I'm having a very weird issue with this.

I've already edited the ITUN to allow child sims to use the interaction, and that works fine. I've also already made a converted version of the huntSniff animation that makes the kids not stretch, and named it with the correct naming convention as 'c_werewolf_huntSniff_x'. I followed this tutorial for converting the animation: https://youtu.be/EmHLZa3GxWE

However! When I try the interaction in-game, the child sims still stretch to use the adult version of the animation, and I cannot figure out why.
The converted child version of the animation plays fine with the animation player mod, and it imports and exports fine in blender. As far as I can tell, it should be working, but its not.

I feel like I must be missing some crucial step, but cannot for the life of me figure out what. It's as if the game is not recognizing the animations as being different versions of the same animation.
I am attaching my package to this post. If anyone can help it would be much appreciated!

Hey there! It seems you haven't matched the group number to the expansion pack, which is most probably causing the issue here. In s3pe, open the resource details of the animation and change the group number from 0x00000000 to 0x70000000 (which is Supernatural). Every expansion pack has it's own group number for its animations and most of the time if you don't match the animations to the number the game it won't work. I hope this fixed the problem!

Thank you so much! I fixed the group number and its working perfectly now!! :D
