Horse stuck at 42 speed at epilogue?

My horse was stuck at 42 speed during epilogue. I looked online and the answers were usually : talk to Hans capon after the ride to neuhof for the speed to go back to usual. so i did exactly that, but my horse speed remained at 42, when i agreed to go with him, the game ends and sends me back to my earlier save. how can i let my horse speed go back to my old speed? its really infuriating for the speed to go back to pebbles speed
