In addition to the aforementioned teleporting into world boundaries, which I was also able to reproduce, I was pulling off the "teleport with bad Axis". Have attached myself doing it on compound, I did it to the similar building on port as well.
Notes on the teleporting into solid objects: I could not crouch. My aim didn't seem to be impaired. Tested that with both glock and scout.
Depending on where, and how thick the invisible wall was, I could teleport back, or to the other side of the wall.
Edit: Also able to teleport from inside Assault to the roof. 2: And from outside in.
