Concerning weird bug arrived today for the first time

Hey there Gix and other fellow support team,
okay so account name is Humxirt.
I am playing Hardcore.

Today, I was rushing someone new in Hc in the server, and the weirdest bug arrived in travincal act 3 Nightmare :

My sorc was built elite (stormshield, full res 75/75/85/75 and 1050 life and
Items : Shako/Mara/2 sojes/Occulus/Stormshield/War travelers and Magefist)
Lvl 86

So basically, was pretty cool and was merely walking in travincal on Manashield.
When life went from.... 1050 to 0 (without even a hit or anything noticed on the screen).

This is the first time this thing happened (got even the guy I was rushing who was following me and was just O_O)
Out of nowhere, didn't take any dmg or anything.
I wasn't even lagging, and so I wanted to know if I was the only one who experienced this weird bug ? (since the disconnection issue...)

Seriously, didn't understand.

Just noticing (not asking to get the sorc back or anything, we are playing hardcore, we know what are the rules of the game but this was lame^^ Already lost chars on legit fights, but that bug... well kinda sucked).

If you have anything on the logs or if anybody experiencing something weird like that.

Take care and enjoy the game (stopping DII for myself, so that came at the right time!)

Thx for everything
