The Prey, Capon's horse gets stuck everywhere

I met Capon at the stables, and ever since he mounted his horse he made his best effort to walk through walls and other obstacles, never really going anywhere. This is fine for the first part because you can skip following him and just meet him at the camp. However, after the rabbit hunting contest he mounts his horse once again, and walks it into a cliff repeatedly. I tried pushing him on course with my own horse, but he seems to snap back to position. If I go too far away from him, he seems to teleport back to his castle and I fail. I don’t want to fail. Any suggestions on how to get around this? Shenanigans with console commands, included.

this is an odd one, because on my first playthrough i had zero pathfinding issues, and now there seems to be a few, i think some of the recent patches broke some things or possibly corrupted save files?

Absolutely: This is my second attempt at a playthrough (I sometimes restart games on my first playthrough once I get a better understanding of the mechanics and decide I want to change the focus of my character) and on the first attempt I had no issue here with this mission. This was before Steam patched it for sure.
