Mictlantecuhtli Drain bug

This is the 2nd time this bug/glitch has happen to me. I was helping a friend get his cuffs i pulled Mictlantecuhtli with full hp and 3 shadows it casted Drain on me it somehow went trew my shadows and it said that i took 0 points of damage,and i died, then the other time this has happen to me was when i was helping my friend again with cuffs was in middle of fight he casted drain on me i didnt have any shadows up on the time but i did have full hp which was around 2,220HP i got hit with Drain for 592dmg and it one shoted me again, think there a glitch/bug with drain sometimes that it gives instance death.
