So, I know the 1.4.2 patch notes specifies that “Player with an equipped bow cannot be dismounted”, but it makes me think it’s just a random “nothing will happen to you, bud” type of thing. Unfortunately whenever an enemy tries to dismount the character while a bow is equipped, the character gets stuck on top of the horse, with no camera movement possible. It is also impossible to dismount/mount, to move (if you release the movement buttons after the bug starts), or anything, really. I’m unsure this report is necessary, but I thought it was worthy mentioning. By the way, the bug happens every single time a dismount maneuver is applied by an NPC onto the player.
Here’s a little footage to illustrate the issue.
