Climbing Death flagged as PVP Death

[Jasede]

If you take so much damage from a climb fail that you are fugued straight (as in, your HP after the magical damage is applied drops to less than -9) your death is flagged as a PVP death, preventing you from respawn.

That's because the last damage you took was incurred from a player: your own PC.

Tested it twice to make sure.
