So freakin' annoying when you get stuck in the gap between two objects (whether they be rocks, crates or whatever) and your character won't climb out... you're stuck there unless you fast travel away, which is complete **** when you're mid mission.

And climbing seems extremely hit and miss.... one moment you can climb 6ft walls, or seemingly scale sheer cliffs and next moment you're blocked by a 2ft rock and can't climb over it.
