Not sure about anyone else, but I'm having a problem with that new ladder at Grantlerhof. I was just playing the map for the first time a few minutes ago as Axis anti-tank soldier and could climb the ladder easy enough, but when I'd get to the top, I had a lot of trouble getting onto the actual roof. On most other ladders you can just keep "climbing" when you get to the top and you'll get "over" it and be on the surface, but with this ladder, when you'd get to the top, it just started stuttering for me.
I tried "jumping" off the top but I'd just slide backwards down the ladder. I tried going up the middle and off to both sides with the same result. I successfully got onto the roof only twice in about 20 tries and that was when I did some weird combination of pressing the crouch button and the jump button at the same time when at the top of the ladder, though it didn't seem to work everytime.
Edit to add:
I think I just figured out the "trick" to the ladder. If you are in the prone position (lying down) and crawl to the ladder to start climbing it, you WILL get onto the roof when you reach the top of the ladder. If you're either standing or crouching when you begin climbing, it will just stutter at the top.
