Climbing isn't overly hard in real life. In videogames though, it's often impossible. Present a super strong protagonist with something higher than a small kerb and they're stranded. That's no longer the case however in Conan Exiles, as the latest update gives climbing to all players.
Alongside the new mechanic is a pretty new engine update, with the game moving from v4.12 to v4.15 of the Unreal Engine. The downside of that cool graphical update however is the fact that, in the words of the developers, "you might find glitchy textures, odd physics and the occasional floating object in the world.". The devlopers are asking players to use the bugreports forum on Steam to report these gravity-defying objects.
