I'm gonna call this a glitch because of how annoying it is. I've gotten Shadowmere and she follows me everywhere. Its really annoying. Every single time I fast travel she is there, ruining my ability to be stealthy. I don't want to kill her, but I definitely want some way to store her at a stable, or tell her to wait at a sanctuary.

Like I said, this doesn't seem like a glitch per se, but it's game breakingly annoying to a stealth character when their horse they cannot get rid of charges in and ruins every single encounter.

I really hope the horse behaviour is tweaked in the upcoming patch. I love having a horse, it really adds to the fun... or it should. But then all that is ruined when they constantly charge into battle/interrupt your approach and die or run away and hide so you can't find them.

I usually try to avoid spoilers but now I actively read them so I can try to prevent any issues that could ruin the game for me. So thanks for posting this, I'll make sure to avoid Shadowmere as she actually seems to be a real nightmare.

Yeah, I'd love to keep her, but she aggros on every single thing close to me ruining any hope of stealth. I hope they address this.
