Hey, this is just a micro bug, if it is a bug at all. There is a ladder on a barn on the map Vossenack that you cant walk up even though you stand right next to it. It's the one thats has dung all over it. I took a screenshot of it so you can see it's position on the map.
PS: The
"How to: Reporting Bugs" sticky has not been changed.
"2) Make sure you have the latest version of the game. Currently that's FH2 2.3." It should be 2.4 now
