Emergency Cranial Defibrillation failure [new way to fail?]

Emergency Cranial Defibrillation did not proc during a horrific vision attempt earlier today.

At the time I had the unwanted haircut debuff from running into the barbershop and was also chainstunned due to a missed interrupt followed by a slam followed by the Haunting Shadows proc.

… So probably somewhere in that trainwreck of bad timing and luck is what caused the cranial debib to not fire.

I had it fail twice on me today. It isn’t just not firing. I noticed a message saying -1000 sanity when it was supposed to give me 500. I was also not healed.
