Tl;DR:

Diablo player Quin69, was less than 20 levels away from soloing to level 100 when his game hung on a load screen causing his character to die from "environmental causes".

Theory is that it was a nightmare dungeon with a lightning damage effect constant. As he teleported, the lightening continues to damage him even though he is stuck loading. Tragic end to a 73 hour run. He also beat the shit out mannequin and a microwave, both apparently undeserving of the punishment.
