Nostalrius Begins - Quality wow vanilla realm (1.12)

I used Divine Shield then Hearthstone at around 2k hp. The casting ended normally, there was still time left on the bubble. The loading screen appeared, since my home was in a different zone. When the loading screen disappeared I was dead, my corpse was flying around. I released my spirit and I was 20123454231201 miles away from my corpse. Its annoying, whats happening, really?

TL;DR: I guess the bug is from an issue with players still appear at the original location and able to be targetted after using hearthstone.
