Stupid death, but how did this happen?

[Celerity]

Somehow, my character instant killed themselves through 600 life. It was a melee attack, so I'm sure it wasn't a case of being yanked in front of my own projectile. The only clue I have is that I was hit with a skill called "Abduction", and then was hit for 300 in one attack but that wouldn't be an instant kill and the death message said I was killed by myself. Anyone know what happened here so I can avoid having it happen again?

Kinda hard when you haven't provided the combat log.
Abduction can move you, so why are you sure you didn't projectile yourself?

[Celerity]

Because I didn't launch any projectiles. This was a purely melee based character. The combat log also showed no evidence of whatever did the other 300 damage, or whatever made me attack myself. There were also no other enemies around or present in the log.

It actually says you were killed by the grave wight. Not sure what that bit at the bottom is doing there.

Neither am I, but that part doesn't make sense either because that isn't 600 damage even counting the DoT ticks.

This game is really solid, a lot of fun and is quite stable but it does have a few bugs. I figure if vault enemies can very rarely spawn outside of vaults and camp the entrance (this actually didn't kill me) attacks can very rarely not show on the log and this enemy used some ability that reflected a large amount of damage back at me. I know those exist, and it would explain the death by self.
