Don't know what happened

My creatures behaved as if I had the Nadin Rift Dancer trait active, i.e. skills that were triggered by dying were activated twice. I only had Mutated Pulse Bat and Trepadation Wight with me to test something. My specialization was Purgatorian, completely skilled.

What exactly happened: Trepadation Wight provoked, then died from Last Words and Mutated Crypt Bat did Murder of Crows. Then Trepadation Wight attacked five times through his trait. Then Mutated Pulse Bat cast Murder of Crows again and Trepadation Wight made five more attacks.
