I'm currently in chapter 6 and every time I take the train I show up at the destination and my horse is back at the station I left from. He wasn't hitched and I've tried whistling before buying the ticket and I've tried riding the horse right up to the ticket window and then getting off and buying the ticket. Nothing works. It's made trains completely useless. My save file is probably over 100 hours at this point but this just started happening like 8 hours or so of play ago. If this has happened to anyone else do you have any idea what's causing this or how to fix it? It's not mod related, I'm playing on playstation. Thanks in advance.

PS: I'm not sure what flair to put since there is no 'help' flair, so I just picked guide. If I need to change it just let me know and I will.
