Use purge, celestial, barrier or any protective buff fails to protect and death or negative status effect is still applied at the same time

[Anything]

Due to how long it takes before the server acknowledges that you are actually protected it is possible to die with barrier, celestial and any other protective buff applied.

The same problem applies to negative status effects too like stun, fear, knockback/knockdown etc being applied while having barrier, celestial, purge etc on.
