Having issues with bots dying and zones crashing

[Congdar]

It's a tough find. One fix was SVN 350 where the check for flash of steel aa was checking the attacker instead of the defender and the attacker had just died from the first riposte. the attacker was a bot and the reference to the bot object was gone.

I'm seeing some other crashes too that seem to be race conditions where the bot has died and it's object is not yet set to null but all of it's data is garbage.

I do have some legit fixes too but i'm still seeing these other bugs.
