Bone cage cast on critical strike bone cage crashes the game

Using bone cage to trigger another bone cage on critical strike end up crashing the game after less than a minute of killing monsters. I've been able to reproduce it every time I tried clearing a map with it (Sandswept Marsh in "Act 6" if it matters).

It does not seem to crash if I use bone storm to trigger bone cage, or if I use bone cage to trigger a different spell. It seems to be only bone cage with bone cage.

same bug 735,258,51.

it crash instance or game depennding on how many monsters hiting.
if its crash instance u get items roll back to.

loock like its crash instance if hit atleast 4 or maybe 3 monsters.
