Hostiles not considered enemies until I dismount

[evilblade]

Hi, guys!

I don't know if it is per say a technical issue, but here's the thing. When I'm riding a horse (and I usually am) and some wolf or skeever attacks it - it isn't marked red on a radar.. and my follower just stands nearby and doesn't kill it  until I dismount a horse and the game finally starts treating this enemy as a... well, enemy.

So how can I help it? Can I somehow make those hostile NPCs to be considered by the game as enemies right away?
