Hi. I'm playing with this mod again and I'm still getting the same error:

https://gist.github.com/HugsLibRecordKeeper/5b1eec114cbac6b901f35e0f74821d86
(All the way at the end - Line 5011)

After the Wyrm (predator) drags back the Desert tortoise (prey) to it's lair, the wyrm is stuck in "Hunting Desert Tortoise" and then "Standing" loop. This annoying bug causes the animal to essentially be frozen until the prey bleeds out.

You told me you couldn't find the error last time, so this time I've provided more information in the hopes that you can diagnose the issue.
