During the quest you are asked to lasso a wooden horse, it tells you to be about 10m and press RB to throw it but right after that (Hard to see because of the market notification ) It says to hit "space" to tighten it or something,  everyone so far been falling beside me,  looks like someone forgot to translate the from pc to xbox. Which would be the "space" button in xbox?

edit: I found out that space in pc is jump so A but bits automatically failing the moment it hits the horse making the quest uncompleted.

I wrote the same thing during the final beta. But PA has ignored my post, I hope they fix this issue. 

Anybody figure this out??

same issue, just went out and caught a horse.
