Sap of Nightmares works for mana but not life

Acolyte of Chayula's passive Sap of Nightmares doesn't seem to be leeching life from chaos damage from neither socketed leech support gems, nor leech on your items. It works for mana, but life seems to not be working both in game and tooltip.

Nobody from GGG or any streamers has noticed this so your only option is to keep bumping this till a GGG employee sees it maybe.

For now, best to just unspec Sap Of Nightmares and use 3 passive points for Elemental leech node on the passive tree. They probably won't fix until 0.4 (or 0.5).
