Mana flask hitting HP - Not the flask that does this - Video included

I posted a different thread about it before I saw this, in my case it seems to specifically be caused if I need the stats from my weapon, after getting some int from passives I still need the int from my amulet but it doesn't happen anymore, only if I need stats from my weapon

Bump, major problem for HC players... Getting your HP or ES smacked is not something thats playable when trying to use pots.
