Platform: PC
Version: 1.7.2
(As far as I’m aware, the bug was present in all earlier versions and never resolved.)
Description:
If you own a horse before starting The Prey, then after you finish that quest and receive Pebbles as a reward before starting The Hunt Begins, it makes Pebbles unusable. You can mount him, but he won’t come when called and you can’t access his inventory. As far as I know, there is no way to switch over to Pebbles from your previous horse, even if it’s worse (which is likely at this stage of the game.)
Reproducing the issue: As stated.
