Random Gzoom deaths : Guild Wars 2 Hacks

Just curious folks, I used this for the first time recently and died a couple of times although combat log shows nothing hitting me etc. I had ported then used a resync skill then died probably 1s~ later. Happened twice within a few minutes. I'm guessing here but thinking that it was a problem with the resync to server and I probably fell to my death or was being hit but the client wasn't receiving the info about the combat.

Sound fairly normal? Nobody around any of the points I was porting to/from as it was reasonably early in the morning.

Can happen if it warps to fast from X location to Y and it's a fall. it's okay

Wall climb also seems to sometimes cause a fall damage on certain walls. Not sure what causes it.
