[Bug Report] Kozilek's Return

[jsw4283]

The AI cast World Breaker with 2 Kozilek's Return in the graveyard. At the time Reality Smasher was on the battlefield under the AI's control. My board was wiped and land exiled from the World Breaker, but the damage did not kill the Reality Smasher, and the Kozilek's Return did not exile. I thought I had just missed something, but the very next turn the AI cast another World Breaker, both Kozilek's Return went on the stack. Again my creature was killed and land exiled. Kozilek's Return still didn't exile and the AI's board did not take damage.

Version: 1.5.49-r-1

PS - I definitely lost this game That many board wipes while I'm playing Abzan Company is hard to beat.
