I actually had a similar thing happen in vDSA today. A group mate died in the air and his body landed on the far side of the arena. When he was finally able to rez, his body teleported to the spot where he died.
It seems the game registers the player as dead in one place, but the player’s body displays in another. Upon resurrection, the player comes up where the game has him registered and not where we see the body.
It was super laggy in vDSA today, so I’m sure that was a big factor.
I've seen this a few times. I think it is a visual glitch. Dropping caltrop where the beam comes from doesn't do anything, but dropping it the one being rezzed does reveal them.
