PC - Father Campbell's Chapel Horse Hitbox/Model
After being downed near the horse on Father Campbell's Chapel, I was able to climb on the back of the horse where the killer was unable to reach me. The bucket next to it was also able to be crawled on to, but I was no fast enough to get a screenshot of it before falling off.
Yes I did come down so I could be hooked after getting the screenshot.
-Crawl onto the back legs of the horse
The bucket does not seem to be consistent, but climbing on the back of the horse does appear to be consistent.
