In the town of Lamentin, on Everon there is a "garden" or a yard surrounded by a fence in the west most side of the town. There are three houses and the one on the north-east corner of the yard has two rooms in it. The left one contains a closet. I ran towards the window while prewieving a mission and got sucked into the closet. I wasn't able to get out and I could literaly see myself inside the closet. It was funny but frustrating. After a while something happened and I appeared outside the building in the garden.
I tried it again and the same thing happened.
Also once in a multiplayer game, I was climbing up the ladder and got shot in the head. I died, but continued climbing up only to collapse at the top.
Funny, eh?
