Remember MoM?? Of course you do... 
It crashed...especially with that Whirlwind spell...really touch and go.
I guess what I getting at is: these crashes impact the game less that trying to cast or do something in the game. Most, if not all, are mitigatable.
Ultimately, it would be nice if Stardock was able to flush out these last few...but if they do, it will be at the cost of balancing concerns...cause it's being released on Oct 23. The frog has spoken.
