Game Mechanics: Corpse next to me but can not be dragged and rezzed elsewhere

[SteveTheDreamer]

I was zoning out of Karnors Castle during a train and my tank died. Baranx
When I zoned back in, Baranx's corpse was visible about 10 feet away in the middle of the hall. He consented me so I could drag it closer to the wall away from the train path.

I was unable to drag his corpse and got the message "too far away to summon this corpse" even when I stood right next to it. So I instead decided to try rezzing him and it worked.
When he zoned in, I saw him for a second and suddenly disappeared and he was dying again. He told me he zoned in underwater and got aggro.

So to me, it looked liked I was rezzing a corpse at the zone in, when in fact his "real" corpse was in the moat.

I tried zoning out/in again, and also relogging hoping it might get fixed but his corpse still appeared in the same spot at zone in even though it was not. When I moved near the moat, then I was able to drag the corpse finally, and when I rezzed him again he appeared normally.

Very weird bug I have never seen this one before, and unfortunately it caused unnecessary death and exp loss.
