I was just messing around on a map and I decided to climb on top of a security camera.

So I stood up and was sticking out the other portal upside down. Also note the invisible man on top of the camera

Now i never noticed this before but if you crouch while doing this, it looks like your head is sticking through, obviously this seems correct.

But when you stand up, instead of your legs remaining, they just vanish? lolwut?
