We've seen many players report a bug when abilities that activate upon landing a critical strike activate inconsistently when used against a target with resilience. For instance, if a warrior has both Enrage and Blood Craze talents, only one may activate when a critical strike is prevented by resilience.

This isn't a bug.

This is due to the underlying implementation for this feature. The game doesn't actually know that hit would have been a critical hit if not for resilience. Instead we've added a small chance to activate off non-crits based on resilience gear. Each ability rolls this chance separately, so they will only occur together if a player is very lucky.
